Im not sure what your first question means?
the latter question is bugged out. should be fixed in a future update!
next update is coming very soon! the 4th of the month at the latest!
assuming that you are asking for the identity of the last forms for akarion and rhianna in their gallery lineup for version 0.15, the answer to that question is TG Wyvern Rhianna, and Trophy Akari. the details on how to get these forms should be in the walkthrough!
