I forgot that they didn't show the part where amai literally just put his cut hand back, and they did say that child emperor was buried somewhere. No one's dead, they're s-class heroes after all. Unless... the plot doesn't follow the webcomic
the other monster did, not him dbdn i forgot which chapter from the webcomic (if it was not shown in the manga) though, it's been more than a month since I've read that
I LOVE HIS BROTHER WHAT HAPPENED TO HIM
