Yuuri of the Destructive Eyes: The Peculiar Relationship Between the Strongest Student and Teacher

The protagonist, having degenerated into a “loser” after being unable to find employment, gets caught up in someone else’s attempt to commit suicide by jumping in front of a train and ends up traveling to another world. The numerous cheat powers he demands from God are all granted to him. But contrary to expectations, these powers bring about disastrous consequences for the protagonist.

Having reincarnated into another world, the optimistic protagonist (Yuuri) starts his heart-warming “training days” with his teacher.
