In Hajime no ippo

#NoHarem

A normal boy got reborn in a HNI mixed with other martial art anime/manga/webtoon etc.
Main world-HNI, Tokyo revengers most probably, then you guys could suggest the worlds for me ;).

Also I am not a great writer or anything so don't expect a masterpiece, I am good and bad.
Also give me ideas or suggestion in the comments, Idc if it's dumb just comment lol.

~~Author out I guess~~
