She probably rejected him
she rejected kisaki coz she's still in love with takemichy even though they are already broke up and never see each other.. in my own conclusion i think he killed her coz he did everything to be at the top of the delinquents yet he can't still have the girl he loves... its like a psycho... like if you are not mine, you can't go to anyone.. kinda （￣へ￣）
i just noticed but kisaki killed hina several times bc he loved her and doesn't want her to end up with takemichy... but that doesn't makes sense bc at the beginning of the story takemichy and hina didn't even see each other anymore... so why would he kill her, i think there's something we still don't know about kisaki
