Persona 3 to 5: Warped Moon (AU timeline)

A tale in which a Persona beginner was chucked into 13-year-old Yuki's body and about how he (unwillingly) transforms himself into a Joker-ripoff. And in which Akechi is a...girl? He hates this world. Everything is not what it seems... (Gender-bent phantom thieves, start in Persona 3's event time, different timeline, AU)
