Grace

Cynthia's alter ego, who takes control when Cynthia's asleep. As Grace, her long hair is tucked up inside the cap she's 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 she's sometimes seen pacing through the corridors in the evening (this is how Tarou first met her and learned of her existence). She's not out every night, however, as Cynthia and Grace share the same sleep schedule and subsequently need to take some time off.
