The Proud War

This is a world where geniuses are like ants. You ask why? Because the people here are all protagonists of novels or anime. Our protagonist is the reincarnation of the gods from heaven, with a body transformed by divine power, and there is an ethereal thing in the protagonist's soul. I have forgotten some of the characters in the novels I have read below. Please correct me if I am wrong. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
