After Being Reborn in a Different World, He Became the Nemesis of the Demon Clan.

[Western Fantasy] + [Another World] + [Adventure] + [Light Novel] The demons invaded the human kingdom. Everyone said that the demons were invincible, but I, Edward, disagreed. From my point of view, goblins and kobolds are just like chickens, and trolls and ogres are just like whelps. Those pure demon species can only be destroyed by talking and laughing. As for the demon general you mentioned? What are you afraid of? Even if it is the devil, if he sees me, he will never come back!
