Ryuto died with an iron bar falling on his head, but a beautiful goddess summoned him saying that he is the Irregular. How will our Ryuto survive in this world? Will he be a hero? Will he randomly do what he wants? Or will he be a villain? We don't know and he does not know too.
Autor: the first chapters are really trash now that I look back at it... but I'm sure it gets better around chap 20+. (It gets better, it doesn't mean it becomes good xD) But, the best thing here is probably looking at my own growth at writing, I started really bad, and now I'm getting better at it. (although it's still trashy)
