We have another candidate with AP capability in the series~ She's a
Kistune named
Luz Ninetei. Introduced in chapter 32, she uses
shapeshifting ability to transform herself into an adult heroine for a live
superhero show.
(Those men have just been converted to APism!)
She's the only character who's had her own AP TF sequence in the series so
far. It would truly be wonderful if the anime gets this far so that we can
appreciate it in animation...
