A young man, after causing the explosion that killed 310 people working in a company, commits suicide. After he dies, he is reincarnated in world of fantasy. He swears to save at least tenfold of the amount he killed in this world. But after realizing he's the son of the demon king, things don't go as planned.  Other stuff: This is not something I'll be working on in a schedule, but more like a project for myself to try learn how to write. I have never written anything before, and I'm intermediate in English at best. I have only read 6 English books in total, so take the book with a grain of salt. Don't except something good, but I'll try to make it somewhat bareable.
