Iron Maw@ To be fair is matter.I mean...who would become the boyfriend of a girl that have the same hobby of the one that kill you're 2 childhood friends?
Also I feel sorry for wave ...i mean if he fail again she will be the one that will punish and will not be pleasant for him.
And I redy to bet that she would do the same with Tatsumi if and with her...honestly she seem some one that punish everyone if they do something that she dont like
