The anime features Akubi from Tatsunoko's Hakushon Daimaou TV anime and Pandora from XFLAG's Monster Strike smartphone game, which also has its own web anime adaptation.
Akubi appears in the original Hakushon Daimaou anime from 1969 as the daughter of the titular genie Hakushon. This October marks the 50th anniversary of the franchise. Pandora is a "girl of wishes" from the Monster Strike smartphone game, who has appeared in the anime adaptation as a mischief maker.
