[So it's very simple. Due to a collaboration with one of my fans in the French version, I decided to add Rimuru from the anime That Time I Got Reincarnated as a Slime and Hatsune Miku from Vocaloid Project. I hope you'll love it.]
[Mini Story : Joke or Infidelity?]
No one's POV
What happened on Shadow's side on April Fool's Day?
Shadow was peacefully sleeping in his room when he received a notification on his phone. He rolled his eyes when he saw who it was from.
In Chelia's phone: Shadow = Chocolate éclair
In Shadow's phone: Chelia = Innocence thief
Innocence thief: Hi my sweetie 🥰
Chocolate éclair: Hey.
Innocence thief: We need to talk.
Chocolate éclair: We're already talking.
Innocence thief: That's not what I meant but anyway. I have something to tell you.
Chocolate éclair: Yeah?
Innocence thief: I... slept with Leon.😥
Chocolate éclair: Huh?
Innocence thief: I'm so sorry, I couldn't resist him.😭
Chocolate éclair: I see...
Innocence thief: You're not mad, right?
Chocolate éclair: No, actually your honesty makes me want to confess something too... I also slept with Yukino and Sherry.
Innocence thief: April Fools!🤣🤣🤣
Chocolate éclair: Huh?
Innocence thief: It was a joke. I didn't cheat on you with Leon. Today is April 1st.
Chocolate éclair: Ah, I see.
Innocence thief: You were joking too, right?👀
Chocolate éclair: ...
Innocence thief: Shadow??😐
Chocolate éclair: Yes?
Innocence thief: YOU REALLY SLEPT WITH YUKINO?!😱
Chocolate éclair: Sorry, I couldn't resist her the first time, and the other times she couldn't walk for weeks...
Innocence thief: IT WASN'T JUST ONCE?!🤯
Chocolate éclair: Relax, we used protection... I think...
Innocence thief: YOU THINK?!😰
Chocolate éclair: Yeah.
Innocence thief: Okay but why Sherry?
Chocolate éclair: I wanted to taste the future.
Innocence thief: TASTE THE FUTURE?!💀
Chocolate éclair: Yep.
Innocence thief: Then you won't mind if I sleep with Sonic and Leon?😌
Chocolate éclair: Leon if you want, but I wouldn't recommend Sonic-he's already busy with Wendy and Carla.🫡
Innocence thief: WHAT? But Carla is a cat!
Chocolate éclair: And Sonic is a hedgehog.😐
Innocence thief: Ah, fair enough.
Chocolate éclair: If you want, I'll come over, we make love, and I'll forget the fact that you asked Sting to steal my t-shirts and bring them to you.🫥
Innocence thief: ...Fine!😍
Shadow turned off his phone and headed out of the guild when he saw Yukino.
Shadow: Yuki, what's the purpose of protection during sex?
Yukino (blushing after realizing): Huh? Well... it prevents having a baby...
Indeed, Shadow didn't even know what protection was. After a moment of realization, he understood that he and Yukino had never... well, anyway.
Shadow (calling Sting): Yo Sting, you're gonna be a dad soon!
Everyone: WHAT?!
Shadow left, leaving the guild members confused.
[End of the Mini Story]
[Extra Story 1 : Rimuru Tempest,from Chao to Slime]
No one's POV
In the beginning, Rimuru was a basic Chao living in the Chao Garden a few years after Chaos (the water monster) awoke, and before Sonic left for Earth. He met Sonic on Angel Island at a time when Knuckles wasn't guarding the Master Emerald. Sonic knew all the Chaos and treated them like his children. One day, Sonic fell asleep in front of the altar with a Chao in his arms. That Chao fell into the water where the Master Emerald was bathing and underwent a mutation. It turned into a liquid monster-not water, but a slime. It didn't leave the water until Sonic left on an adventure and didn't return for 9 years.

Rimuru emerged from the water but couldn't find the one who had transformed him. He decided to go in search of him. Over the years, he discovered he could become human, had nearly divine powers, and eventually teleported to Earth using his own magic without a portal ring.
Today (after the Grand Magic Games), he was still searching for Sonic. He had heard that Sonic had joined the Fairy Tail guild and was now a powerful mage. So, Rimuru headed toward Magnolia. He had to pass through Hosenka and was walking through a forest when he sensed something strange. He heard a girl screaming-she was in danger.
Rimuru found himself facing a violet-haired mage with a sword on her left. She wore an ornate white blazer with gold trim and a large collar over a white shirt and red tie, white gloves up to her wrists, black tights tucked into white knee-high boots under a ruffled white skirt. It was Kagura Mikazuchi.
She was fighting serpents emitting a poisonous cloud. She didn't seem in trouble, but the poison was slowing her down. Rimuru, immune to poison, came to her aid. He sliced the snakes at Sonic-like speed and opened his mouth wide to swallow the spreading cloud. Kagura was amazed but didn't have time to speak as she fainted due to the poison.
Rimuru: Oh no, I hope I'm not too late...
He picked her up and carried her to a hill nearby, laid her in the grass, and sat five meters away. An hour later, she woke up.
Rimuru (seeing her wake up): Oh, you're awake? It was really dangerous back there. Luckily, I came in time-I even managed to remove the poison from your body.
Kagura, startled, stood and prepared to draw her sword. Rimuru panicked and was ready to draw his as well.
Kagura: You... you deserve... a meal...
Rimuru (confused): Huh?
Kagura (calming down): Who are you? And why did you save me?
Rimuru: Oh, I'm Rimuru, Rimuru Tempest. And I saved you because... uh, I don't know...
She looked at him in disbelief, then giggled-something she rarely did.
Kagura: Thank you anyway for saving me. As I said, I can thank you with a meal-if you're hungry, of course...
Rimuru (excited): Are you kidding? Of course I'm hungry! Let's go!
He grabbed her hand and ran with her to Hosenka. They arrived in under 30 seconds.
Kagura (amazed): You... you're fast!
Rimuru: Yeah, I know. (seeing her wind-blown hair) Oops, wait, your hair...
He smoothed her hair with his hand. She blushed and pushed his hand away to fix it herself.
Kagura (blushing): No need, I can handle it!
Rimuru: Uh, okay. Shall we go in?
They entered the first restaurant they saw. While waiting for their food, Rimuru started a conversation.
Rimuru: By the way, you haven't told me your name.
Kagura: Oh right, sorry. I'm...
Rimuru (interrupting): Kagura Mikazuchi, member of Mermaid Heel, participant in the Grand Magic Games. Your beauty and fame precede you.
Kagura (chuckling): Thank you... (realizing) Wait-how do you know so much about me if we've never met?
Rimuru: I watched the Grand Magic Games. I saw your fight with Leon. Your gravity magic is amazing.
Kagura: Oh, that makes sense. And thank you.
Rimuru: By the way, what were you doing in the forest earlier?
Kagura: I was tasked with eradicating those snakes spreading poisonous fog. By the way, how did you cure me? That poison doesn't even have a medical antidote.
Rimuru (lying): Uh... I guess I just got lucky.
She stared at him suspiciously before nodding.
Rimuru (changing the mood): Can I ask you something?
Kagura: Go ahead.
Rimuru: Why didn't you draw your sword back there? I know it's none of my business, but... are you saving it for a special occasion? To draw it in front of someone?
Kagura looked down for a moment.
Kagura (lifting her head): Interesting question. I intend to draw it in front of someone I hope to see again one day.
Rimuru: Hmm, can I know who?
Kagura: ... It's Jellal Fernandez.
Rimuru spat out his drink.
Rimuru: THE Jellal Fernandez?! The one who destroyed the Magic Council and made Sonic and the others suffer?!
Kagura: Yes, that's him. You know Sonic?
Rimuru: Oh, um, yes. I'm actually looking for him. I heard he's in Magnolia. I was on my way when I found you.
Kagura: I see. Why are you looking for him?
Rimuru: It's been a long time. We promised to see each other again one day.
Kagura: I hope you find him.
Rimuru: Thanks. By the way, why do you resent Jellal so much? You haven't said why.
She looked away, hesitant. Rimuru watched, wondering what was troubling her.
Rimuru: We can drop it if you want. I think I'm asking too many personal questions.
Kagura: It's okay. Strangely, I feel like I can trust you, so I'll tell you... It's because he killed my brother Simon.
Rimuru (thinking): (Why am I even asking when I already got that info when I absorbed her to remove the poison... oh well.)
Kagura: Simon died protecting Erza from Jellal. He was my only family. I can't forgive Jellal. That's why I'll draw my sword and kill him. He'll pay for taking Simon from me.
Rimuru looked at her sadly. He didn't know what to say. Kagura turned away and stood up.
Kagura: Excuse me.
She went to the restroom to collect herself. A few minutes later, their food arrived. Rimuru had ordered shrimp; Kagura had steak and lettuce. She returned and saw Rimuru already eating.
Kagura: Sorry to keep you waiting.
Rimuru: Oh it's fine. You needed time to clear your head.
Kagura: Thanks for understanding.
Rimuru: Don't mention it.
They ate in silence. Afterward, Rimuru insisted on paying the bill. They walked outside.
Kagura remained silent, so Rimuru restarted the conversation.
Rimuru: Kagura, I'm sorry about Simon. I know how hard it must be to lose your brother.
Kagura: Don't worry. Once I find Jellal, he'll die by my sword.
Rimuru stopped and blocked her path.
Rimuru: Kagura, if you kill him, will it satisfy you?
She looked away.
Rimuru: Kagura, look at me.
She did.
Rimuru: Will you be satisfied if Jellal dies?
Kagura: I... I don't know...
Rimuru: Let me tell you what will happen. If you kill him, you'll go down the path of vengeance. It will change you. You'll be consumed by anger and keep killing. One after another. And one day you'll wake up regretting all the lives you've taken-for the rest of your life.
Kagura: Rimuru, Jellal killed my brother. He deserves to pay.
Rimuru: Yes, I understand. You're angry and hurt. But killing him won't solve anything. Yes, Jellal did horrible things. I'm mad too that he hurt your friends. But you're better than that, Kagura. The only way to be free is to forgive Jellal-not for him, but for yourself. It will calm your soul and stop you from going down the revenge path. I'm sure your brother would think the same.
Kagura lowered her head, moved by Rimuru's words. She knew he was trying to help. She started crying and hugged him.
Rimuru (whispering to comfort her): Shhh, it's okay. Let it out.
She cried for a few minutes, then calmed down, ended the hug, and wiped her tears.
Kagura: Thank you so much, Rimuru. You really helped me today.
Rimuru: It's nothing! Glad I could help. Feeling better?
Kagura: Yeah, it'll take time, but I'll be okay.
Rimuru: Well, I should get going. Still got a long road ahead.
Kagura: Already?
Rimuru: Yep. I didn't plan on making a stop.
Kagura: I see... so we'll see each other again?
Rimuru: Probably. I might come back after seeing Sonic.
He ran off at full speed, leaving the town and heading toward Magnolia.
[End of Extra Story 1]
[Extra Story 2 : Hatsune Miku,the global Idol]
Sonic's POV
It was supposed to be a normal day at the guild until news spread in Magnolia: the world-famous idol Hatsune Miku was coming to Magnolia for one of her world tours. Lucy, Wendy, Carla, Erza, and Mirajane were talking about it while I was sitting at a table with Natsu and Happy a bit further away. Thanks to my Dragon Slayer hearing, I could hear their conversation.
Erza: So she's coming today?
Mira: Yes, her concert starts tonight in front of the rainbow cherry tree.
Lucy: I'm so excited! I'd pay a fortune for her autograph!
Wendy: I managed to collect all her albums. Her voice is amazing!
Mira (teasing Wendy): A voice that might even charm Sonic!
Wendy (panicking): Huh?! What do you mean charm?!
I was so focused on their conversation that I didn't notice a hooded person walk in and approach the counter.
???: Hello!
Mira: Hello, how can we help you?
???: Yes, I'd like to know if someone named "Sonic the Hedgehog" is here.
Huh?! Who's asking for me? And... I feel like I know that voice!
Mira (pointing to where I'm sitting): Oh, he's sitting right over there.
The person turned toward me and her hood immediately fell off. I saw a girl with twin tails and blue hair wearing an idol outfit looking at me in shock. Damn it, I already know who this is. I didn't even have time to stand before a pair of breasts had already crashed into my face.

Miku: SONIC, I MISSED YOU SO MUCH!!!
Miku had thrown herself onto me, making me stumble under everyone's stunned gaze.
Me (enjoying the softness of her breasts): Miku, what are you doing here?
Everyone: YOU KNOW HER TOO?!
Lucy (shocked): Is that really Hatsune Miku?
Natsu: Wendy has an older sister?
Wendy (pulling Miku off me): Stop! Since when do you know Sonic?
Me: Well, actually...
Wendy (on the verge of tears): You're cheating on me, aren't you?
Me: WHAT, NO!
Mirajane, I knew you'd put that idea in her head.
Carla (angry): Then why did you throw yourself at her chest?
Me: She threw herself at me! Don't you start too!
Erza: Let me guess-you saved her once, and as a thank you, you two hooked up?
Me: NO!!!
Makarov: So where do you know her from?
Me (annoyed): SHE'S MY SISTER!!!
A silence fell. Everyone burst out laughing 30 seconds later.
Gray: You're kidding, right? Since when do you have a sister?
Wendy: Yeah, you would've told me already!
Me: Maybe I forgot that detail.
Makarov: Forgot? How do you forget you have a sister?
Happy: And you could think she's Wendy's older sister-they almost look alike, except she has...
Wendy (disappointed): Breasts, yeah I know...
Me: Anyway, let me explain.
I picked Miku up and set her on a table. Before she could speak, I stuffed a leek in her mouth, which she started munching on rapidly.
Me: So, Miku is a girl I met when I was a kid. She had no family, and we spent a quarter of our lives together on Mobius. One day, I helped her pursue her dream of becoming an idol by leaving her with Omochao, and as you can see-she made it.
Wendy: Why didn't you tell us?
Me: It didn't seem important...
I got hit on the head with a leek by Miku.
Miku: Just say you didn't want us to form the same duo as before, so you ran off on an adventure and forced me into a solo career.
Every time she spoke, it sounded like she was singing.
Me: But you're doing great, aren't you?
Miku (pouting): It would've been better if we were still together.
Lucy: Wait, what do you mean, "duo like before"?
Miku: Sonic didn't tell you he plays guitar?
Wendy: We knew he could play background music without us noticing, but we didn't know he played an instrument.
Me: For the OSTs, she's the one who taught me how to do it.
Mira: Now that you mention it, during her concerts, there's never any speakers or a mic when she sings.
Me: Her voice is natural, that's what makes her so popular. (I handed her another leek) Anyway, what are you doing here?
Miku (mouth full): What do you think? I came to see you, and I've got a concert here too.
Chip: Sonic, why are you giving her leeks?
Me: She loves them. I figured she'd show up, so I prepared in case she wouldn't leave me alone.
Miku: Speaking of which, we have to go!
Lucy: Where?
Miku: I scheduled Sonic as tonight's Guest Star!
Me: WHAT? Without asking me??
Miku (sticking out her tongue): Of course!
Me: I haven't sung in ages!
Gajeel (dressed in concert gear): Then I'll replace him!
I Spindashed him away.
Me: Definitely not.
I looked at Wendy, who was sitting and thinking.
Wendy: So she is your sister?
Me: Yes, stop panicking. Don't worry!
Miku (taking my hand): Come on, let's go?
She pulled me to leave the guild.
Wendy: Huh? Wait!
Wendy, Carla, Chip, Erza, and Lucy followed us. Before leaving, I gave Miku a cloak to keep her from being recognized. We walked through the streets of Magnolia toward the park.
Lucy: So Miku, how did you meet Sonic?
Miku (still eating another leek I gave her): Actually, I was part of a lab experiment called Vocaloid. They gave us supernatural vocal abilities. Since I was their best creation, they overused my voice, but one day Sonic saved me and we've been inseparable ever since.
Lucy: That explains the number 1 on your left arm.
Wendy (giggling): Typical Sonic.
Miku (pouting): We formed our musical duo. We were the most popular on Mobius until Sonic decided to go off adventuring and left me with Omochao.
Me: Why do I feel like you're mad at me?
Miku: Of course I am! Because of you, Sega was dissolved!
Everyone else: Sega?

Me: That was our duo's name.
Miku: Most of our songs were created together. The rest, I had to perform alone even though Sonic composed them.
Erza: Like?
Miku: "Can You Feel the Sunshine," "My Sweet Passion," and "Super Sonic Racing."
Lucy (shocked): Wait, Sonic wrote Super Sonic Racing?? Your most popular song??
[Note: The songs Miku sang are the female vocal songs from some Sonic games.]
Miku (laughing): He wrote the lyrics, but I had to sing them since he wasn't around.
The girls looked at me with excitement, and I turned bright red with embarrassment.
Me: Anyway, I still can't go with you. I'm part of Fairy Tail now.
Miku (excited): Oh, that's awesome! What's that?
The girls stared at her, stunned.
Lucy: Uh, it's a wizard guild.
Miku: Wizards?
Me: Yeah. We use magic to help people.
Miku: So you sing to help people?
Me (blushing): What? No way! I use Lightning.
Miku: Can you make it rain too?
Me: No!
Miku (excited): Can you make leeks fall from the sky?
Me: NO! Let's just get you to the park for your concert.
Miku: But I haven't visited the town yet...
Me: Can it wait?
She gave me puppy eyes. Damn it, why can't I resist those? I looked away, but she stepped in front of me and kept begging.
Me (giving in): Fine, we'll take a tour.
Miku: YAAAY!!!
I closed her mouth so she wouldn't get noticed by the public.
Me: But keep it low-key!
She nodded. After a long city tour, her stomach growled.
Miku: Sonic, I'm hungry!
Me (shocked): You ate 5 leeks on the way!!!
Lucy: I know where to go!
We followed Lucy to 8Island. We had spaghetti while Miku had a leek-only salad, eating like someone was chasing her.
Me: Could you maybe eat slower!?
Miku (mouth full): It's... so... good...
After finishing her plate, her belly had inflated. The girls looked at me like it was my fault.
Me: What?
Carla: She's gotten huge-Is that normal?
Me: Usually...
Wendy: What do we do?
Me: Leave her like that?
Erza pinched my cheek.
Erza: Let's find a way to give her a quick diet.
Lucy: A quick diet?!
Me: Guys, it's not necessary.
Erza: What do you mean? She's bigger than Droy!!
But then the girls noticed that Miku was slim again.
Wendy (shocked): How...?
Me: Miku can't get fat. It's a little magical trait of hers.
Carla: That's incredible!
Miku: I'm full! Shall we go?
Me: Let's go.
After paying the bill, we continued toward the park, now in sight.
Wendy: Look! I see the park!
An earthquake stopped us. There was chaos near the park-we saw it suddenly rise 300m into the air, lifted by blue tentacles.
Lucy: What is that thing?
Miku: An octopus?!
Me: Only one way to find out.
We ran to the crater left by the lifted park. Seven tentacles held it in the air. Thankfully, no civilians were trapped up there.
Erza: Lucy, help me cut the tentacles. Sonic, Miku, and Wendy-get up there and see what's going on.
Me, Lucy, Miku, and Wendy: Got it!
Chip changed his wings and lifted me up after I grabbed Miku by the waist. Followed by Carla and Wendy, we reached the floating platform where we saw someone at the podium-a turquoise, liquid orb watching us. It had seven tentacles holding up the park.
Me: Don't tell me it's...
Wendy: Chaos!?
Chip: It's been 7 years and he's still alive?!
Carla: He looks smaller than before.
I launched a lance of energy, but the liquid absorbed the magic instantly.
Me: Uh... wasn't it supposed to vanish and reappear like before?
Chip: He's strong enough now to absorb attacks.
Chaos launched a tentacle that grabbed my left hand and pulled me toward it. I resisted, but it was hard-until it absorbed me.
Miku, Carla, Chip, and Wendy: SONIC!!!
The liquid prevented me from breathing for a moment, but I created an explosion that freed me, shattered the liquid, and neutralized the tentacles. The park started falling back down and crashed into its original crater, creating a dust explosion. Erza and Lucy had evacuated the civilians. We were briefly blinded by dust until we saw Chaos reform as a water orb.
Wendy: I don't know what you want, but you better leave us alone!
Me: Guys, wait! That's not Chaos-it's not even water, it's...
???: That's right, I'm a Slime!
The liquid orb started to take human form. It was a man my height with long light-blue hair, yellow eyes, a blue suit, and a sword on his back, looking at us.
Me: Who are you?
???: It's been a long time since we last met.
He sped toward me so fast only I could see it coming. As I was about to defend myself, he hugged me.
???: I missed you so much, Dad!
Everyone: DAD?!
[End of Extra Story 2]
[Extra Story 3 : The Legendary Blues]
Sonic's POV
Me: Huh?! What do you mean, Dad?
???: Come on, you don't recognize me? It's me, Rimuru!
Me: Uh, I knew a Rimuru, but he was a Chao!
Rimuru: Who do you think is standing in front of you now?
I looked at him with a confused face.
Wendy: Sonic? You know him?
Me (ignoring Wendy's question): Wait wait wait, how did you become human in the first place?
Rimuru: I used the power of the Master Emerald and turned into a slime.
Me: Well, I'm starting to think letting Knuckles protect the Master Emerald wasn't such a great idea.
Rimuru: Oh, by the way, Miku, I forgot to give you this back.
He handed her a microphone-shaped hairpin.
Miku (realizing): Wait, you're the basic Chao I used to play with when Sonic was away!
Rimuru: That's right!
Carla: Okay, but why are you calling Sonic "Dad"?
Rimuru: Because he took care of me like a son. Not just me, all the other Chaos too.
Wendy: Awww that's so cute!
Chip: But why did you attack the park?
Rimuru: Oh, I just wanted to get Sonic's attention since I had just arrived. Well, shall we go?
Me: Go where?
Rimuru (taking my hand): You're joining Fairy Tail with me!
Everyone: Huh?
He tried to pull me along but I stopped him.
Me: Whoa whoa whoa, wait a minute, I can't keep up anymore-first Miku comes back and now I have a son (looking at Rimuru)... or a daughter?
Rimuru: Oh, you can choose whichever pronoun you want, I'm non-binary anyway.
A silence fell.
Everyone: WHAT?!
He pulled down his pants, and instinctively we all covered our eyes, but then noticed he had no private parts.
Rimuru: See? I'm neither a man nor a woman!
Me (embarrassed): Okay okay we get it, pull your pants back up!
He got dressed again.
Lucy: But how is that even possible?
Erza: It's true that in the Chao Garden, we never asked if there were males or females.
Miku: Why are you only coming now?
Rimuru: I wanted to try the adventurer's life for a bit. Then I heard about your concert in Magnolia-perfect time for a reunion.
Carla: Sonic, what else are you hiding from us?
Me: Nothing, I swear!!!
We headed to the guild and told the Master everything that had happened.
Makarov: Hmm, I see... So Rimuru, what kind of magic do you use?
Rimuru: Oh, I'm a jack of all trades!
Makarov: Alright, but what exactly can you do?
Rimuru: Absorption and power copying.
Me: How about you show us what you're capable of?
Rimuru: No problem! But I want to face four specific people.
Makarov: Who?
Rimuru: The four strongest in your guild: Natsu, Erza, Laxus, and Sonic.
We were all surprised.
Laxus: So you think we're the strongest in the guild?
Erza: Too bad Gildarts isn't here.
Natsu: Perfect! I wanted to blow off some steam!
Me (panicking): Why am I included?!
A few minutes later, we gathered behind the guild on the sandy shore near the lake, while others watched from above.
Rimuru: You can attack first!
Natsu: Let's go!
Natsu charged with a flaming punch, but Rimuru blocked it with one hand and the flames vanished like they hit water. Rimuru countered with a spinning kick that sent Natsu flying into the lake. Erza dashed in with her cheetah armor, striking with her swords, but Rimuru easily parried each blow with his own blade. I came in with a blue electric Spin Dash, but he knocked Erza aside and sent me flying with a slash. Laxus tried to punch him, which Rimuru blocked with crossed arms but still felt the impact.
Enraged, Natsu shot out of the lake and attacked again. Rimuru vanished just as the punch connected and reappeared behind me, creating an explosion that threw me into Natsu. Erza used her Heavenly Wheel armor and launched dozens of swords at him, but Rimuru transformed into a slime and absorbed them.
Erza: What the...?
He returned to human form and fired the same swords back at her. She blocked some, but others hit and launched her into the air. Rimuru pointed his finger and fired a laser that pierced her heart without opening her chest.
Lucy: Oh no, Erza!
Rimuru: Don't worry, she's still alive.
Erza collapsed and reverted to her original armor. Natsu did a Fire Dragon Roar, but Rimuru took the hit without flinching, then started absorbing the flames just like Natsu does.
Gajeel: Is he a dragon slayer???
Levy: Who is he?
Wendy: He took down Erza with just one laser!
I threw a lightning spear, Laxus launched a thunder halberd-Rimuru caught both and hurled them at Natsu, who struggled to block and collapsed, paralyzed.
Laxus: Looks like it's just us two now.
Me: Perfect! Let's show him the power of the Thunder Duo!
We both charged up with electricity.
Me and Laxus: Roar of the Thunder Dragons!
We fired a huge yellow and blue lightning blast at him. Rimuru slashed it in two with his sword. We smirked as the two beams reversed and homed back in on him. He jumped and flipped to dodge, but didn't expect them to circle back to us.
Me and Laxus: Combined Spell: Divine Judgment of the Infinite Storm!
I rushed at Rimuru in electric turbo mode and slammed him down. He turned into slime and wrapped around me. He didn't expect Laxus above us, descending with a lightning punch. The impact cracked the ground and blinded everyone with wind and dust. When it cleared, Laxus had his fist on my head-Rimuru was gone.
Rimuru: Wow, your combined move is amazing! If I were weak, I'd be dead right now.
He appeared 5 meters away, unscathed, glowing with more colors than a rainbow.

He teleported, and suddenly I saw him in front of Laxus. Too late. He punched Laxus in the gut and sent him flying into the guild wall, which shattered.
Raijin Unit: LAXUS!!!
I tried to punch him at full speed, but he dodged with just a head tilt. He grabbed my arm, pinned me to the ground, and charged a laser.
Rimuru (smiling): Well, I think we've had enough fun!
He helped me up.
Me: Already?
Rimuru: Yeah, if we kept going, someone might not survive-and I want to join the guild, not destroy it.
Makarov: This kid has incredible potential.
Back at the guild, after Rimuru healed Natsu and the others, we all stood before the Master.
Makarov: Alright, after thinking it through, you can join our guild.
Me and Miku: Hooray!!!
We stamped the guild mark on his right hand.
Makarov: Rimuru Tempest, you are now a full-fledged member of Fairy Tail!
Mirajane: By the way, I forgot to ask something, Rimuru.
Rimuru: Yes?
Mirajane: Are you a boy or a girl?
Rimuru (smiling): Neither.
Everyone burst out laughing.
Gray: No need to ask-we all know he's a guy with long hair.
Rimuru pulled down his pants again, and this time everyone screamed and covered their eyes.
Me (pulling his pants back up): You don't have to do that every time to prove you're non-binary!
15 minutes later, we celebrated Rimuru's joining. At sunset, I was on the guild roof with him.
Me: So, happy now?
Rimuru (in slime form): I've always been happy! This world has so much to offer me.
Me: ...By the way, I'm sorry.
Rimuru: Why?
Me: If I hadn't made you fall into the water, you wouldn't have turned into this.
Rimuru: Oh, I don't blame you. Thanks to you, I'm even stronger than Zeref.
Me: We'll see about that. So, are you doing missions alone or...?
Rimuru: Oh, I don't plan to stay anyway.
Me: What do you mean?
Rimuru: I just wanted to join the guild so I could visit more often. But I have my own things to do.
Me: You're going adventuring?
Rimuru: Yep! There are so many worlds I haven't explored yet.
Me: Wait-worlds? I only know Edolas and Mobius.
Rimuru: My powers are transdimensional-that's why I said I could probably kill Zeref.
Me: Ah, I see.
We came down from the roof, and Team Natsu was waiting.
Natsu: So you're leaving?
Rimuru: Yes.
Gray: You'll come back, right?
Rimuru: Of course. Gildarts always comes and goes, right?
Erza: It was a pleasure meeting you, Rimuru.
Rimuru: Same here. Count on me to protect the guild in my absence.
Happy: That sounded like something Gildarts would say!
I hugged Rimuru.
Me: I love you, son!
Rimuru: I love you too, Dad!
Natsu: I'm lost. When did Wendy give birth to Aquarius and Rimuru?
Lucy: Aquarius changed form, and Wendy didn't give birth to Rimuru, Natsu...
Miku: Where do you two think you're going?
Me and Rimuru: Huh?
Miku: You forgot we have a concert tonight?
Rimuru: We?
Miku (smiling): Yes, you're in it too!
Me: You're not really making us do this, are you?
Chip: Actually, with your hair colors, you'd make a great trio!
Miku: The Hair Force One!
Me: What kind of dumb name is that?!
Miku: Well, "Hair" because of our hair.
Rimuru: I suggest... The Legendary Blues.
Natsu: Awesome name!
Me: Yeah, that's got style!
Miku looked sad, but smiled again when I gave her a leek.
Me (smirking): Hey Rimuru, one last favor since we won't see each other much.
Rimuru: What is it?
I whispered something to him.
Rimuru: Hmm... doable... oh now? Okay then.
Rimuru turned into a slime and suddenly extended tentacles that tied up Miku,Wendy, Lucy, and Erza.
Lucy (panicking): W-what's happening??
Erza: I'm stuck!
Wendy: Sonic??
Me: Phase 2!
Rimuru heated the tentacles, melting their clothes-even Erza's armor.
Girls (embarrassed): KYAAAA WHAT ARE YOU DOING???
Me and Chip (pulling out cameras): Say cheese!
We took photos of them naked for 10 minutes before anyone noticed. I almost got executed by Erza, but we made it to the concert where Rimuru, Miku, and I sang "His World," "What I'm Made Of," and "Super Sonic Racing" while the guild girls sat VIP.
