Nina Nina (ニーニャ・ニーニャ, Nīnya Nīnya) is a ghost-like girl who dwells in the Roaring Cavern. She was a novice summoner from another island, but being horribly bad at reading maps, ended up at that island while finding ingredients for her teacher. She ended up in a boat and dozed off, and woke up as a spirit. She found out a Summon Creature named Passeau had stolen her body, and often comes back to taunt her with it. She had tried unsuccessfully many times to take back her body. She's a caring person and tries to be as helpful as possible to the main character. Eventually, with the help of the main character, she gets her body back from Passeau.
