OH GOD KIREI. Basically he is Byakuya's least favorite person ever next to Zouken. He's terrified of him and he hates him and he'd do whatever he could to undermine him, given the opportunity. Kirei tormented him and created KotoShirou and the two of them had hideous influence on Shinji. Basically, Kirei made his life a living hell and he wishes he could kick his face in but he'd never have the guts to. But due to him he also has a weird thing about God being full of shit. The only good thing that ever came from Kirei is that if he hadn't picked on both of them, Byakuya & Kariya would have gone on hating each other. He's also attached to Shirou but he can't thank Kirei for that because... reasons...

How does Rin feel knowing Sakura got to go home in Byakuya's timeline?
