Of those few places not yet under Persona's control is the free town of Kabuki-cho, also known as "The Dark Side of Tokyo". Within the town, under the leadership of a woman named Mai, is a small resistance group called Messiah. Into this world steps a man who takes the sobriquet of Kabuki-cho: Darkside. Sealed up in another dimension eighteen years ago by Persona Century, Darkside now returns to aid Messiah using his unique mystic power of renewal.
