The wrap-around jacket band on the second volume of Sayaka Mogi´s Switch Witch manga has announced that a new Pupa project is in the works and, with that, the advertisement has the ambiguous teaser saying ´Attains even lower depths…!!´
The translation seems to be a bit awkard though, unless the staff and the mangaka themselves admit that Pupa (the anime, atleast) is a complete and utter mess. If you recall, Pupa is 5-minute 12-episode anime short that aired sometime last year, naturally, it received quite an uproar for the obvious reasons. Personally, if this trainwreck of a hilarious series gets a second season, I´ll laugh. Hard.
With that said, Hakusensha‘s Young Champion magazine will reveal more information at a later date.
