The second-year curriculum barely differed from the first.
Academic subjects remained the same, just more challenging. Afternoons no longer included physical conditioning. Students who hadn't dropped out by now had extracted chakra. By steadily progressing through six years, they'd either become genin endorsed by a jonin for village priority training or join other departments as fresh talent.
The odds of wasting six years and reverting to civilian life were slim.
The next five years would teach intelligence gathering and assassination skills.
For Izayoi, these posed no challenge—borderline tedious. After a few days, he abandoned his plan to attend in person, dispatching a Shadow Clone to classes instead.
His real body stayed home, training.
Though he couldn't practice elemental jutsu indoors, he could develop ninjutsu. Creating ninjutsu typically demanded mastery of nature or shape transformation, but as a transmigrator, Izayoi knew one technique required neither—just ample chakra.
That technique was the Fourth Hokage's brainchild, inspired by the Tailed Beast Bomb, developed over years into an A-rank, non-elemental, seal-less ninjutsu: Rasengan.
Naruto's signature move, used from childhood to adulthood and spawning variants, was the only technique in the original story with its full training method revealed.
That training arc left an indelible mark. No Naruto fan could forget it, Izayoi included.
But he wasn't mastering Rasengan as a trump card. As mentioned, he aimed to develop a new ninjutsu.
Rasengan, a seal-less technique crafted by the Fourth Hokage, held special significance in Konoha. Only the Fourth, his teacher, and his disciple wielded it.
If Izayoi used it publicly, he'd draw the scrutiny of Konoha's leaders. Without a plausible explanation, suspicions would arise.
That wasn't his goal.
Instead, he planned to use Rasengan as a foundation for a new seal-less ninjutsu: Ultra Hurricane Chain Spheres.
Also called Multi-Great Jade Tempest Sphere, it was an anime-original technique Asura Otsutsuki used against Indra. Similar to Naruto's Planet Rasengan, it involved creating a large energy sphere—slightly smaller than a Great Jade Rasengan—infused with five smaller, spinning spheres akin to standard Rasengan.
Like Rasenshuriken, it could be thrown or launched, detonating in six consecutive explosions. If the main sphere burst, the five inner spheres would scatter, striking enemies independently.
Like Naruto's elemental Rasengan variants, it could incorporate the five chakra natures or combine them, akin to the Third Hokage's Five Release Great Combo Technique, yielding cataclysmic power.
Without his red-tier Otsutsuki Bloodline and purple-tier All-Attribute Constitution, Izayoi wouldn't dare dream of this. Mastering Rasengan would've sufficed.
But the Otsutsuki Bloodline's seal-less talent, paired with All-Attribute Constitution and purple-tier Chakra Control, gave him the means to turn an anime-original into reality.
With his chakra control, he mastered Rasengan in a week.
Next, he'd expand it to basketball size without letting it burst, then attempt to form smaller spheres within.
That phase couldn't be practiced at home. A single explosion would be catastrophic.
So, he bided his time, awaiting the Uchiha clan's downfall.
On May 15th, that day arrived.
Afternoons typically held two or three classes, with survival exercises every few weeks to gauge progress. Even then, school ended around five.
But today, Class 1's second-years had four classes. The final survival exercise stretched until dusk.
The Uchiha clan's compound, near the Naka River, sat on Konoha's outskirts. Without Body Flicker, Sasuke's trek home took time.
By the time he reached the compound, night had fallen, a full moon rising, tinged blood-red against the fading sunset.
Izayoi's Shadow Clone glanced at Sasuke's retreating figure as he jogged from the school gates.
He knew that after tonight, the mildly aloof Sasuke, indifferent to grades, would vanish.
In his place would emerge a cold, driven avenger, obsessed with scores and clan honor, easily provoked by taunts—a Sasuke vulnerable to emotional turmoil.
Though tragic, Izayoi eagerly awaited that moment.
He'd waited a full year.
The next day, news rocked Konoha, rippling outward via spies to engulf the ninja world.
After the Senju's decline, the Uchiha—Konoha's foremost clan, arguably the ninja world's greatest, famed for their peerless one-on-one prowess, Copy Wheel Eye, and genjutsu mastery—had fallen.
The culprit wasn't their rival Hyuga, Konoha's leadership, or another village, but the clan head's eldest son, thirteen-year-old Itachi Uchiha.
Itachi's name spread like wildfire, branding him Konoha's—and the ninja world's—youngest S-rank rogue ninja.
Stepping out that morning, Izayoi overheard villagers buzzing about it.
This was monumental, rivaling the Nine-Tails' attack in Konoha 48.
In mere years, Konoha lost the Fourth Hokage and his wife, numerous elites, and now its premier clan.
The village had entered its weakest era since founding. Once boasting shadow-level ninja too numerous to count—capable of defeating four villages single-handedly—it now clung to an aging Third Hokage as its sole Kage-level strength.
Post-Nine-Tails, the Cloud exploited Konoha's vulnerability.
Losing the Uchiha should've drawn more predators, yet the coming years remained eerily calm.
Clearly, other villages sensed something amiss.
