Sian

Maid with Princess Iris.
She is a newly appointed maid who was personally accompanied by the king as a condition for attending Iris's garden party.
She is Iris's hobby, and her maid outfit is cute and decorated, but she has a taciturn, cold expression, is always calm, and lacks emotional ups and downs. She is quick-witted but inflexible.
She claims to have no sense of direction, and she often wanders around the castle, but the extent to which she really is unknown.
A mysterious maid that even Iris doesn't know what kind of past she has.
