After the Chaos, Everyone Became a Monster Except Me

Hey, what's going on? I think this book is pretty good, well, at least for me. Why is there no one? Did I come too early, or is this book not good-looking? I think it's okay. That's for me. Well, anyway, from what I've read so far, it probably means that the protagonist also has a monster. Some kind of peace agreement was reached, allowing them to live in that half-human, half-ghost state. Then I joined this bureau in 2013.
