Nanashi is an LRIG who appears in the anime Lostorage incited WIXOSS. She is created from the memories of her selector, Hanna Mikage, specifically from Hanna's desire to remember the repressed details of the day her brother Yuuto died. Nanashi has long pale blonde hair and wears a cream dress with black tights. Her personality is teasing and playful, and she frequently offers lighthearted quips during conversations. She does not understand why humans place such importance on memories. However, beneath this outward demeanor, Nanashi possesses a sadistic streak; she takes pleasure in Hanna's despair when Hanna eventually recovers her painful memories. Nanashi's role in the story is to serve as Hanna's LRIG, battling alongside her in the Selector Battles. She is confident in Hanna's abilities and supports her throughout the competition. As Hanna recovers her memories and experiences emotional turmoil, Nanashi reveals her darker nature. At the conclusion of Lostorage incited WIXOSS, after Hanna wins all five of her gold coins, Nanashi returns to Mayu's White Room and disappears. Her notable ability in battle is summoning a large black cloud that obscures the vision of her opponents, which she uses to gain an advantage during fights.
