"Chuichi", the cat, which was created by hikki, will be on sale in Japan. There will probably be a cellular phone strap, keychain, and more. Detail and more information will be up in this website as soon as I get more information about it.

8/30 Update:
Well, looks like there's going to be a T-shirts, postcards, and pin badges for the original Chuichi products. These items will be on sale on the beginning of September.
