Yeah, that’s really the only place I found Gaki merch, and I looked all over on three different trips. When I was there they had the character socks, Oba-chan shirts, a sweets tin, and a few miscellaneous things. They had a couple of busses left from the No Laughing specials, but this was a few years ago. Sometimes you can find the Figuarts Downtown figures or the Hamada gachapon used at various stores in Nakano Broadway.
