Shu Itsuki has a love of dolls and antiques. They often spend all day, or at least most of it, up in their atelier making clothes, sometimes asking for you to accompany them but claiming it was "because Mademoiselle wished for it". Mademoiselle is a doll which Shu is attached to and makes dresses for. Shu speaks like an old person, at least according to others. Shu says "no" instead of "no". Shu's favorite food is baguettes. Only cooks their own food and doesn't eat things made by others.
