Author : Kinugasa ShougoIllustrator : TomoseshunsakuAs Ayanokouji and his classmates begin their second year at the Advanced Nurturing High School, they're greeted by a fresh gauntlet of exams and a fresh batch of rather unique first-year students. They'll have to get to know each other quickly, because the first special exam pairs the first-years with the second-years on a written test--with only the second-years facing expulsion if their team performs poorly! Worse yet? It seems one of the new first-years is also from the White Room. Can Ayanokouji avoid expulsion while sussing out the identity of this hidden foe?

Lassen, a young man who has failed at everything in his life, has had enough. Disillusioned with the world, he decides to end it all. But instead of dying, he wakes up in a parallel world, armed with a strange system that can accomplish anything he desires. Trapped in his room, reading novels and savoring every page, he has no intention of participating in the fast-paced world outside.Yet, despite his desire for peace, the world changes every time he makes an appearance. Everyone treats him like a genius, a being capable of disrupting the very fabric of reality, without lifting a finger. A powerful system, a new life, and a world that adapts to him: why complicate things when you can have everything without effort?The Genius System tells the story of a man who, although having everything to change the world, prefers to watch it evolve from the comfort of his room, through the pages of his books.

Traveling through the world of Naruto, he is just a four-year-old boy who has no talent, no family, no blood, and no tailed beast.

Unexpectedly, after completing the Jain test, the system suddenly awakened.

Since then, he has drawn the glittering fruit, the shaking fruit, the dragon-killing magic crystal of fire, the magic eye of death, Geass, the blood of the ancestor giant, the eye of reincarnation, the eternal kaleidoscope writing wheel eye…
