I suppose it's my turn ? Hmm, nobody asked me ?
Well, that's only a glimpse (fortunately) of my complete collection but here is my two treasures that I acquired 26 days ago (yeah, that day is carved in my mind) : a Shikishi of Nagisa signed by Itaru Hinoue (the signature is handmade, not a copy) and the AIR Analog Collector's Edition.
What ? That scrap of paper ? Don't pay attention to it, it's nothing... yeah... absolutely nothing.
