Kaguya-sama wa Kokurasetai Shousetsu-ban: Tensaitachi no Renai Jinrou-sen

The setting is Tsukikagekan, which stands on a solitary island owned by the Fujiwara family. In addition to the members of the student council, Moeha Fujiwara and Kei Shirogane are involved in a battle similar to a werewolf game over a treasure that can make wishes come true!
