King & Prince release their 18th single! It serves as the theme song for the film "The Ogre's Bride," starring Ren Nagase in a double lead role. With lyrics that delicately and romantically depict an encounter with a precious person, and a mature waltz infused with Japanese elements, it is a beautiful love song that can be described as a new artistic direction for King & Prince! The first press of the regular edition is scheduled to include "Waltz for Lily" and two additional songs. It features a three-panel case. It includes a lyrics booklet and one Type D trading card.
