Tom senpai; lets not start a chain of crack theories :p

According to the latest manga spoiler; Genryusai is dead (which I expected considering Aizen sama got damaged and he didn't even stay in the attack for long). If it was inside him; Aizen sama would have taken it already.

I doubt Toshiro used it; he had noooo time to prepare; even if it only takes a spilt second.
