There are as many lives as the number of musical instruments. RETUNE is a small used music store in a country town. Guitars, basses, drums, and keyboards... are sold and bought here every day. Kogure Tsuru (22), who unexpectedly took over the store after the death of her father, comes into contact with the circumstances of the owners who come to sell their instruments and their past... People who have given up on music, people who have lost sight of music, people who have been hurt by music... these are the people who will be touched by the "wonder" that Tsuru has to offer. These people are guided and saved by the "mysterious power" of the vines, and take a new step forward in this story of rebirth.
