Starting an Holy Grail War in an Multiversal Anime-World

Victor, who was on the verge of loosing his virginity after a date with a young lady cosplaying Raiden Shogun, unexpectedly transmigrated to a multiversal anime world. As long as he could bend the world's perception with warped logic, he could grow infinitely stronger! From then on, a sky screen appears across the northern and southern hemispheres, broadcasting radically remixed videos. The entire multi-anime world's style gradually becomes bizarre. Yukino Yukinoshita declares: "Standing perpetually at the hill of swords, drunk alone on victory... My body is definitely made of infinite swords, Unlimited Blade Works!" Rikka Takanashi proclaims: "The kaleidoscope is invincible, the invisible boundary, all attacks cannot touch it! Come, Saber, let's see whose Noble Phantasm is the true absolute defense!" Kaguya Shinomiya asserts: "Even if I bear a Lostbelt, and need one hand to hold up the Throne of Heroes, I, Kaguya Shinomiya, am still invincible in this world... Hayasaka, save me!" Countless anime characters obtain mythological inheritances, shocking the entire world! Through his influence, this world gradually ascends dimensions from a low-magic world, until it becomes an eternal and indestructible realm!... Note: This story is fundamentally based on a translation of an existing Chinese fanfiction. However, it should be considered more of a light rewrite or adaptation rather than a direct, literal translation. I (the person adapting this) have taken the liberty to add, remove, or modify certain elements, plot points, or character interactions from the original source where I felt improvements could be made, or where certain aspects didn't quite resonate. Therefore, please do not expect a perfectly faithful, 1:1 translation of the original work. Think of it as an inspired retelling aimed at providing a smoother and potentially enhanced reading experience.
