I, or someone, will have ta kill him to get his soul free. After that... I'll be honest, I've never done it before. [he admits it a bit sheepishly] But... I've told you, haven't I? That I'm a weapon, a sword, as well as a soul-eatin' beast. But I don't think I ever told you what purpose I serve, and you probably didn't talk much to Ichigo while he was here. [he chuckles; Ichigo wasn't the world's friendliest guy, and he didn't talk about himself much] We're a Shinigami, after all. "Death God". Part of his job is literally to shepherd souls, and my job is to make sure he can do his job. What kind of zanpakutou would I be if I couldn't manage to ferry one measly ghost from point A to point B, huh?
