So there was this police guy who always use excessive violence with straight face. And there's this yakuza who loves violence and hurting ppl. Yakuza guy asked the police to join him. Police kept saying no.
Until one day, police saw yakuza got fucked and he's like horny. Yakuza guy said he could fuck him. Some time later that, yakuza asked police to join him again because he said they're similar. Police guy ENJOYS hurting ppl too and that yakuza guy has always been drawn to him.
Long story short, police joined yakuza.
