A glass of sake
Looking over the plume of smoke rising from the top of my beloved cannon, I begin to think about what I have set in motion. That kid, he's a strange one. He doesn't rely on any kind of special power or any extra training besides what Urahara gave. Just pure gut determination and what he believes, just like brother. I begin to wonder what makes those kinds of people go, what makes them tick and how they live.
He reminds me of you, Kaien, but of course you always did what you wanted to do, what you believed was right. You might of been the only exception in our perceptions of the shinigami. Or maybe we were just disillusioned. If you were in my spot, would you be doing the same thing?
Pouring myself a glass of sake, I ponder what they meant to you, "I'm sorry brother, I'm going to help a shinigami; like the one who killed you." But what if you were still alive? What if that shinigami never killed you? "If you were still alive, and I didn't do anything for them, you would probably scold me." Saying something like 'shinigami or not, if they're in trouble, help them!'. I think you'd do it anyways, "Just because you loved the shinigami, and died as a shinigami." To you, young Ichigo, I wish you luck. I bring the glass of sake and drink it whole. It's sour.
