I don't want to spoil everything so read this at your own risk. But I can assured you that it's not confirmed that Dan killed MC's brother. Anyone who's new to the series please ignore this thread if you can.
Spoilers:
No, Dan didn't kill Yoshikazu. It's another guy who likes Hitomi (Trace MC's brother) and was angry that she got pregnant after being raped. The guy killed MC's entire family and then set the thing up as murder-suicide by Yoshikazu.
There's more to it than that, but that's the gist. I don't want to spoil anymore.
I wonder how it would ties to Brutal?
