Ever since a traumatic experience, Nukui Hibiki has been a recluse, with his biggest hobby being the use of vocalization software to create and upload songs online. One day, he receives an email from a group of fifth-grade girls asking to meet and discuss something with him. The three girls, who have grown up together like siblings, request his help in expressing their gratitude to those who have cared for them. Their devised method? Putting on a successful concert at a venue filled with memories.
