Found raw chapters. I can't read Japanese but from what i understand, Hiroki is not the one who murdered Sawaguchi family. It was his sister's teacher i think. He captured and tortured that guy and ask Sawaguchi to finish him off but he refused. Sawaguchi even save that murderer from fire (Hiroki set his cabin on fire and disappear into the fire).
I read somewhere that Hiroki got like "crush"/obsession on Sawaguchi's big bro and that's why he bullied him? Idk
Wait. He actually a villain? Dan Hiroki from "Brutal"? He not a vigilante justice seeker? All that killings are just in his nature and he never care about the victims at all? Or Sawaguchi's family actually were bad person? But he raped a girl though
