Kuchen Baum (クーヘン・バーム Kūhen Bāmu?) is the no-nonsense concierge of Villa Angel in Galaxy Angel Rune. He is a transvestite and works several side jobs including a hostess in a seedy bar and the manager of a beauty spa. Much of the humour surrounding Kuchen comes from the fact that only the Rune Angel Troupe know he is actually a man. In Episode 4 Natsume Izayoi repeatedly attempts to find out if he is a transvestite but is always cut off by her Suzuki servants.
Kuchen's name comes from a reversal of the name of the cake Baumkuchen.
