An energetic middle school girl named Kyan Nanafa lives in Okinawa with her grandmother who runs the Kame Soba soba shop; her beautiful older sister Nao, a high school student; and her younger sister Kokona in elementary school and with a strong ability to sense the supernatural.
One day, Nanafa witnesses a seal fall off of a Chinese banyan tree, unleashing three spirits living in that tree. These spirits include Nina and Lana, both jimunaa spirits. Iina, the third spirit, is an incarnation of an Okinawan lion statue. As more and more spirits start appearing, Nanafa’s life and that of her family becomes a lot less peaceful.
