does anyone understand what's going on or am I the only one lost here

They let Makoto play the mob boss for a some time, while his bro was behind him and manipulating everything along with some elders. The other blond got mixed up cuz he liked Makoto's "sex toy", who in reality was undercover for another gang. Makoto went to get his toy back and now everything comes crushing down.

Don't forget the three-way incest. Between Makoto,Ai and their mother (the only reason Betty is relevant to the story)
