Bruh idek but does he know they were siblings
She hasn’t told him yet oof
!!!SPOILERS!!! So basically, Rize has found out that her brother Misaki or something was actually a really bad person. He was a rapist, a thief, etc. At first Rize didn't believe that her sweet onii-chan could be so horrible. But then, Kairi & Tochibana pulled up with proof of other people talking about how bad he was. So yeah, now Rize has no other choice to believe so. And she also knows that Kairi's murder was "justified".
Can some explain of what going on in the chapter
