Well, anyway, I guess we can start using it. But only for images where "hat as distinct character" is present. If someone starts tagging it on every image where Suwako is wearing the hat, I'll have to hit them.
Before we start using it, we need to move the artist currently there. On her website she gives her name as "ๆๅฎใใ". something_kei. Any ideas on the name?
