In een andere wereld heeft een steeds groter wordende Zee van Sneeuw het planeetoppervlak overspoeld. De mensen worstelen om te overleven terwijl ze rond de routes van een enorme baanboom leven, waarvan de takken zich hoog boven de grond in het hemelmembraan verspreiden. Er komt verandering in deze stervende wereld nadat Kaina, een jongen uit het hemel membraan, een meisje van de oppervlakte tegenkomt dat Ririha heet.
