What other merchandise is there?
I've seen a Haruka statue, some t-shirts from cospa.com and tha's about it...no capsule toys or whatever...
I only have a few posters from Dengeki Ani-Maga/other japanese character/anime magazines, kgne "mousepad sticker" and the one I treasure the most, a KGNE Promotional Clock. The dealer I bought it from said you had to send a coupon or something in from the magazines and you'll get it if you're lucky when they draw you. Usually named "__XXX__ Present/Gift page" or whatever.
