Some info from Perfume City:
"This year will be held an -Act Against AIDS- event by the AIDS educational events.
Guest artists and actors are Porno Graffitti, Perfume, DEPAPEPE and others.
This event which was started on 1993 (this is its 15th year), will be held in three different places (Osaka, Nagoya and Tokyo) with different artists, and then, as a special 15th Anniversary commemoration, an event will be held next December 1st at Nihon Budokan, gathering all artists from each previous event."
I think it's really nice that Perfume is participating
