Im looking for the manga where MC is a half demon. I think his mother is human but his father is one of the powerful demon lords in hell. he looks human but he discovers he has demon powers of immortality. You can cut him, and he will just regenerate his body parts. He goes to school in Hell. there, he meets a Skeleton who self-proclaims as his rival. I think the Skeleton guy has an english name. Andrew or Adam? Not sure
Satou-kun no Juunan Seikatsu Yup, I'm sure it's this. It's funny but the last update was 2 years ago...
Ive expected this but i still made this thread with a hopeful heart and now im crushed again actually in other manga sites, the latest chapter (6.5) was 5yrs ago
