Is it Dororo?
No, I think it's actually only a few years old and probably ongoing. Maybe 2021 released. Started reading when it only had 1 vol. By now it should have 3 or more
Thank you anyway
They made a modern dororo manga around when the new anime came out. It really sounds like dororo lol. Here is the modern one https://www.mangago.zone/read-manga/dororo_to_hyakkimaru_den/
Tbh it really does. But it's not, as much as I love Doritos (DORORO ) auto correct
The genre tags didn't fail me for once
It's a historical, supernatural manga taken place in Japan. The main character is a demon hunter or something.
The main character is a boy, black hair and empty eyes. He has a "little brother" that follows him and he takes care of. I guess it's just the two of them but the brother isn't actually his brother, it's a demon he probably made a pact with ig.
The cover should be a boy and a red background, thanks (｀_´)ゞ
