so, the way I understand
their ultimate skills are basically taken from P3's fusion spells
Yosuke: Cadenza (Orpheus + Asparas)
Naoto: Infinity (Vishnu + Ananta)
Chie: enhanced Best Friends (Forneus + Asparas)
Kuma is basically Fuuka's Oracle. It's either that or the Fusion Spell Summer Dream (Titania + Oberon)
those costumes look nice especially those Velvet ones
Chie wearing Elizabeth's and Kanji looks like Theodore
...
Naoto, da fuq is she wearing on that one image?
as for the epilogues
Kanji's hairstyle.... looks weird
Nanako with long hair is <3
