Queen of the Tower. An absolute idiot. An airhead. She's so strong her alias is the "Undefeated Cat Queen." She speaks very childishly. She is incredibly stupid for a Queen (important). She calls Guest "Maid-san." She is Moru's sister, but there's over a 100cm height difference between them. A beastman. Fights using a scythe.

The Queen's younger sister. More mature than Kuro, she likes cool things and black aesthetics. She loves salmon bento boxes. Her race is a ghost, known as the "Ghost of Trauma." Surprisingly, she can understand human egos and such! But she doesn't use it much, only for things she finds interesting. She has a great body. Usually plays the fool but occasionally plays the straight man. A free spirit. Speaks politely. Uses magic and firearms (?!). She calls Kuro "Onee-sama."

Head Maid. Serious. Her cooking is insanely good (good enough to win a Grand Prix). A hard worker who does nothing but play the straight man. Childhood friends with Rayshina, though they often bicker; usually, they get along well. Has an older sister named Ruby. A fairy. Fights with a massive hatchet on her back. Calls Kuro "Queen Kuro." Battles Rayshina at least once a day.

A maid. Even stupider than her younger sister. Solves everything with brute force. The type to water flowers with boiling water. Can't cook. She's competent as a gatekeeper... probably. A fairy. Fights with an axe. Calls Kuro "Kuro-san."

A spirit of the universe. The tallest among the group. Shy... maybe? Childhood friends with Sapphire, though they often bicker; usually, they get along well. A frequent guest at the tower. Fights with violence and magic. Calls Kuro "Kuro-san." Battles Sapphire at least once a day.
