Urashima Tunnel – Once you enter that tunnel, you can get whatever you want, but at a price. Kaoru Tohno, who seems to have an elusive personality and traumatic past, and Anzu Hanashiro, who is struggling to reconcile her ideal image and true-to-heart attitude, team up to investigate the Urashima Tunnel and get what they want. This is an unforgettable summer story of nostalgia and sprinting in a remote countryside.
