[X] Let Zangetsu stay released
[X] Admit you have it if asked
I don't really feel like we should bother trying to be sneaky. We have a small timetable, one we've never been shy about.
We've basically been telling anyone who'll listen that we'll blitz through the academy and got a job going to the world of the living in a year or less, it doesn't make much sense to me to keep actual progress on that path hidden.
Ichigo isn't nearly sneaky enough to actually pull that shit off, considering that Aizen is in play. Not to mention, it's going to come out sooner or later, and it's not totally game-changing like a Bankai would be. Significant and impressive? Yes. A powerful secret that must be kept hidden lest he lose the element of surprise/invite terrible shit onto himself? Not really.
I say fuck it.
Sides, it'd make sword bro happy. He's already a cranky bastard, no need to make him shittier.
