"During the Final Fantasy XI Japan Vana-Fest, it was announced that Shantotto, an NPC female Tarutaru Black Mage of Windurst, will be playable in Dissidia. She will be voiced by Megumi Hayashibara and it is currently unknown which side she will be fighting for or if another FF11 character will act in opposition against her. However, one of the images of her clearly shows her standing on the same dais as the Warriors of Cosmos. Another shot though shows her fighting against the Warrior of Light, even using her EX-Burst on him. It's a little hard to tell what her EX-Mode costume change is from these shots - it almost resembles the Sorcerer's Attire Artifact Armor set from FFXI, but not quite. Her EX-Burst will probably draw upon the game's concept of a Magic Burst, it is too early to say at the moment. The description of her being passed around on the Japanese web is - 'A Tarutaru NPC in FFXI, one of Vana'diel's premier black mages, one possessing an unheard of genius talent, who during her time as an adventurer bravely infiltrated the Empire of Aht Urhgan under a false name.' " Here is a Famitsu article. It confirms it + a few screens.
