Square Enix is working on a brand new and original Final Fantasy game for DS that will be released in Japan this autumn.
Dubbed Four Warriors of Light: Final Fantasy Gaiden (translated from Hikari no Yon Senshi: Final Fantasy Gaiden), the game follows a 14-year old boy whose birthday is ruined when the King summons him to rescue his daughter from a witch.
His adventure plays out in typical party-of-four, plenty-of-menus fashion - although one where mana (or magic) points have been replaced by a Charge command.
Customisation will play a more important role, as equipment changes are reflected by the appearance of your character - a mechanic JRPGs usually forego.
FFXII and FF Tactics character designer Akihiro Yoshida will work on the game.
There's no word on release plans for Europe.
