A true fan is measured by two things: their field of knowledge, and how much materialistic rubbish they've collected in the name of obsession!
What bits and pieces of Bleach merchandise does everyone have?
Myself, I have these two posters:
Rukia-chaaaaaan... *drools*
I've also got Rukia's glove, a sweatband with the glove's symbol on it, Chad and Orihime action figures, and Renji and Byakuya plushies! Vwee!
