As a virtual anime game player, for unknown reasons, he actually entered the Naruto world. Treating the entire world as a game, Hyuga Akira plunged headlong into it. The [Bandit Set] dropped by bandits made his stun skill dominant in the early game. The [Sharingan] dropped by Konoha created a synergy with the Byakugan. He obtained Demon Slayer [Lightning Breathing] and Baki [Demon Back] and [Demon Brain] from Cloud Village. He also obtained Fairy Tail [Arc of Time] and [Fire Dragon Slayer Magic] from Iwagakure. He picked up the [Devil Fruit Fragment] dropped by Kirigakure. Wearing the [Vongola Sky Ring] from Sunagakure, the flames of his fighting spirit ignited. As experience points accumulated...

After experiencing all the anime, Altair got bored and decided to bring the anime heroes into the school world.

A goddess splashes water on a priest, a vampire draws a gun and confronts the Demon King, and the invincible Ainz Ooal Gown can't even break through a wall! Problem children are forced to attend classes obediently! Explosive Mages become mere fireworks displays, and the Demon King Rimuru can only perform purifying expired lunchboxes. When Lelouch and Demiurge clash in wisdom! When Benimaru draws his sword against Ainz, Anderson uses the Bible against Aqua, the Vampire King Alucard becomes Inspector Megure's subordinate, and the Shadow Lord starts working as a Meituan deliveryman? The Undead King is actually a network administrator! Two goddesses of wisdom can't solve math problems, Yujiro Hanma gives Frillien a PE lesson, and the invincible Jotaro Kujo is actually a model student! Dio isn't afraid of sunlight, and the Tyrannical Demon King is actually a transfer student! Tanya finally discovers the existence of X? Kazuma is actually envious of Subaru Natsuki! Goto watches a robin sing?

To satisfy Altair's perverse tastes, the anime protagonists have no choice but to spend their exciting and fun school days here before successfully graduating and returning to their own world.

Lin Yu transmigrated to the world of Demon Slayer. Awakening the Character Inheritance System, he immediately inherited the legacy of the blind swordsman, Fujitora Issho. Thus, a swordsman of unparalleled skill and mastery was born… “This swordsmanship!” “Is this really a sword that a human could wield?!” Kibutsuji Muzan collapsed to the ground, his face filled with unprecedented terror. Kibutsuji Muzan once again experienced the terror of being dominated by that figure four hundred years ago, even more terrifying than before. “This oppressive feeling…” “Perhaps, compared to us, you are the monster.” Upper Moon One, Kokushibo, stared intently at the man standing before him. Having experienced the terror of that man four hundred years ago, Kokushibo could better understand the terror of the man before him.

"Okay then."

"If I blow it up, you'll be able to fight me, right?"
