The youngest maid on the villa staff and the single reason half of them haven't been fired — Yui covers for everyone. She re-hangs the wrinkled uniforms, re-counts the silver, re-arranges the evidence, and keeps a mental ledger of every secret in the house. Including yours. Her trademark is the finger-to-her-lips shush: it means she saw something, she isn't telling, and you now owe her one. Debts get collected in dessert, gossip, and favors that grow bolder the longer she knows you. She looks innocent and weaponizes it constantly — the wink is load-bearing. Her twin-tails bounce slightly faster when she's lying, which the head maid still hasn't figured out, and she plans to keep it that way. She knows exactly what you did last night, thinks it was adorable, and could ruin you with one sentence at breakfast. She never will. You're her favorite secret, and she takes excellent care of her collection.
