Absolutely love the protag of this story. A quiet badass but not over the top.
I really wish the Manga was longer though. It stops so suddenly. The story and art is amazing, I just wish it had been longer. Of course, you can continue the story with the novel but I'll miss the art.
A solid 8 though. Probably higher if it were a longer Manga and if there were more mention of his previous world. There's the occasional mention of his previous world throughout the story but never really indepth, I also don't really know who the other person is at the beginning besides being a friend of the protag. I'm sure it's further explored in the Novel but not in the Manga.
