Ok, I just finished the Soul Society arc, and I noticed that not a single person actually dies. Sure, they get wounded and bloody and all, but they always recover... and fast too. For example, Renji, gets cut to shreads his captain, but somehow survives (though 4th captain saves him, I suppose). But Ganju most likely would have been killed by the same move, seeing that their power differs so much. Not that I would any of the main characters to die, but you get my drift.
