This is my confession...
You know what I think would be cool?
Well it would be cool if in some Zaraki gets beaten up very badly in some fight and he falls over on the ground.
Then in true Shonen way he starts a monologue about how he should've been stronger.
Then he lifts his sword over his head and speaks how he could've been stronger if his sword would have given him some power.
Then he goes "yeah... Like that would happen... Not after I have treated you like this..."
Then a brief pause.
Then he starts to whisper "I'm sorry..." And then suddenly his eyes open wide and after moment of "wtf"-face his trademark devilish grin comes back to his face.
And then he goes "I'M SORRY! *********!!!"
And then Bankai or Shikai or whatever the shit happens.
(****** because who knows what his sword's name will be)
