Thomas Alfade, who has founded a successful pasta company in his world, takes his grandson and successor Sirius with him to the Nekoya to do some business. Upon trying the restaurant's spaghetti with meat sauce, Sirius learns that all the pasta and sauces that have made the Alfade company famous are actually mere imitations of the Nekoya's menu. Later, Adelheid, a sickly princess who once went to the Nekoya with her late grandfather Wilheim, once again discovers the door to the Nekoya. There, she tries the "clouds" she had tried as a child (a chocolate parfait), filling her with memories of her grandfather.
