Neko ni Hakucho, Hotaru ni Koban猫に白鳥、蛍に小判（カドコミ）; A Swan for the Cat, Gold for the Firefly; Cats and Swans, Fireflies and Gold Coins.; Un cisne para un gato, oro para una luciérnaga; Лебідь для кішки, золото для світлячка

Art teacher Hase Hotaru is confounded by one of her students, Nekome Yuna. Yuna fell in love at first sight with Shiratori Ako, a contract teacher at the same school, and she cannot do anything but pursue her. However, Ako has a quirk, the depths of which are yet unknown. A student hopelessly in love and the adults around her being yanked around. A new and vibrant work by Yodokawa that plays out with the school as the stage!
