Have you ever met/saw mafia movie? Even you got beaten up for just bumping one.

he was jealous of Asaichi and beat and raped him because of Yoru. only the excuse was his sister, but he didn't pay that much attention to that as much as he wanted to punish him for Yoru furstly for stealing him as potential lover and for misstreating him.
kids who didn't understand that shouldn't read such hardcore yaoi :)

dont act like you know yaoi that much. you dont even make yaoi.
Why did the Yakuza rape Asa? Just because he slapped his sister or because he mistreats Yoru?
That seems like a VERY harsh punishment for either case.
