^You really don't have to go outside of gantz for an Inaba comparison - It's fairly similar to how Sei died. She kicked a fair bit of ass, then once it looked she had the edge, she turned to look at kurono, "not bad, eh kurono?", let her guard down, and was brutally pawned.
That being said, I seriously doubt Inaba will be back - This is about as great as he could get, he coming back to his old whiny self would cheapen his death (not that this isn't a brutally cheap way to go - I mean, last chapter, oku announces the appearance of a boss, and this chapter it appears... on top of inaba) , and Oku's final line has an air of finality about it. That being said, Kurono AND Katou looking back at him indicates that the present gantz team has two leaders now (both of which were shocked wordless by inaba's achievements... except maybe Katou - he was probably like... so this is how I look with one less limb."
@Blue: It hasn't been happening all that much lately, Cali and me discussing - he's been far more active than me. Did you know that once upon a time, i had more posts than him?
