Alphonse Flügel, an admiral of Duchy Samanark, became a regular of the Nekoya while shipwrecked on a remote island for twenty years. Three months after he is rescued, Alphonse manages to find another door to the Nekoya and once again gets to savour his favorite dish, curry rice. Meanwhile, "Kuro", the black dragon of death who had banished herself to the moon to avoid inadvertently killing innocent lives, discovers a door to the Nekoya just as Alphonse is asked to sample the owner's newest dish, chicken curry. As "Kuro" becomes addicted to the chicken curry and orders excessive quantities of it, "Red Queen" informs her that she needs money to pay for food. Thus, "Red Queen" asks the owner to hire "Kuro" as an additional waitress to pay off her accumulated bill.
