Not to many people here seem to know about Persona. I love it, P4 being my favorite. I can't wait to play as Yu Narukami (or Shoji, which ever you prefer) and kick some Aegis ass! Kanji looks like a ****ing beast too.
As Drakilla said, Persona bases itself around Japanese Gods, Demons and other spiritual stuff. Each character gets their own Persona and their Persona gets its own special ability such as the main characters main Persona in P4 (gotta say main persona cause he's the Fool Tarot 0. He can have as many personas as he wants. He can even mix them too) is Izanagi, a Japanese god. Izanagi's ability is lightning. Yosakes Persona Jiraiya's ability is wind. Yukiko's persona, Konohana Sakuya's ability is fire (I hope you're not confused by this).
Kanji is gonna kick some major ass in this game. I already know it.
