Shiba Kaien

“When we die, our bodies disintegrate and become part of the reishi that make up Soul Society. And when that time comes...where does your heart go? It gets passed on to your nakama (comrades). If you pass it on to them, then your heart will always live on within them. Kuchiki, that's why...you must never, ever, ever die alone. Got it, Kuchiki?”

“Whenever you fight from this point on, there is one thing you must never do. Which is...to die alone.”

“Every time you and I interact...a bit of "heart" is born between us. Heart isn't something inside you. But whenever you think, whenever you remember someone, that's when heart is born. I mean, if you were the only one alive in the whole world, heart wouldn't exist, now would it?”

“The fight to protect life and the fight to protect honor——that's Captain Ukitake's policy. But you know, Kuchiki...I think that in the end, those both end up being the same thing. ...Heart.”

“[when Rukia asks why she is in the Gotei 13] What the hell?! That's so obvious! To "fight" and to "protect"!”

“[dying] Kuchiki, I dragged you into this...I'm sorry. You must've been scared. Thanks, Kuchiki. Thanks to you...I can leave my heart here.”

“[possessed by a Hollow] Why do you keep calling my name so? Are you that worried about me? Are you that much in love with me, little girl? If you love me so much...I'll eat you first!”

“Uncoil the seas and heavens, Nejibana!”

“But don't forget... as long as you're in my division, I'm on your side until death and beyond.”
