Come on, guys who are close friends and share some significant, singular bond like having double zanpakutou? It's like a perfect setup for fangirling!! I'm a fan of Ikkaku and Yumichika too - there's a scene later on where Ikkaku is nearly killed by a much stronger opponent, and Yumichika watches with what seems like absolute, almost creepily detached calm... and you can tell that it's the hardest thing he's ever done. ^^

LOL I should have known you had something to do with it~
