Grace  

, グレース

Cynthias alter ego, who takes control when Cynthias asleep. As Grace, her long hair is tucked up inside the cap shes wearing, and her charisma becomes a polar opposite, making her quite talkative and adapting a stubborn attitude. At night, she mainly controls the security of Hanaukyo Mansion with help from MEMOL, a large computer system which she designed on her own, although shes sometimes seen pacing through the corridors in the evening (this is how Tarou first met her and learned of her existence). Shes not out every night, however, as Cynthia and Grace share the same sleep schedule and subsequently need to take some time off.
