I agree with your theory on the relationship Shuuhei initially had with his Zankaputo. But then Tousen probably sabotaged it with his teachings. I bet if Kazeshini had a chance, he would have torn Tousen apart for that.

Heh. How much you wanna bet he was utterly delighted that his shikai was released in the traitor's head?

No, not bad for a first fanfic at all.

It's good even if it is a first fanfic.

I've never read a female hisagi fanfic before, it's awesome!
