Bodybuilding Harem, Do you lift sister? (R18-Crossover)

Bodybuilding, Harem, Sex, Crime.
A man from Earth is reborn into a fighting and hentai world's massive crossover.
As an OC from KOF, Terry and Andy Bogard's youngest brother, to be specific.
If I had to describe what I want to do with this, let's say it's Nostalgia+Hentai Harem.
You'll get characters from Hentai parodies, old Arcade games, Tekken, HSD, Baki, GOHS, Streetfighter, Streets of Rage, KOF, etc.

Warning: This is mostly a slice of life. The gym/bodybuilding stuff won't start before chapter 30.
