This paper toy is Yamato Suzuran Waha, a cute anime girl that was widely prevalent on 2chan and 4chan. While becoming popular on 2chan, and then crossing over to 4chan, Waha~ is a fanart image of a character named ‘Suzuran’ from a hentai game called ‘Suigetsu’. The reason she is called ‘Waha~’ is because she yelled it out after every one of her lines in the game.
SuperWaha~ is a placement of videos using a higher pitched version of the song SuperGirl by Papaya. It was later made into a game.
