The Tunnel to Summer, the Exit of Goodbyes

Finished

夏へのトンネル、さよならの出口

Kaoru Touno stumbles upon a mysterious tunnel that matches the description of an urban legend: the Urashima Tunnel. It is said to grant any wish in exchange for years of the visitor's lifespan. Haunted by the death of his sister Karen in an accident five years ago, which he feels responsible for, Kaoru sees the tunnel as a chance for redemption and to undo his past mistake.

His exploration of the tunnel's surreal and unpredictable rules is complicated when his aloof classmate, Anzu Hanashiro, secretly follows him. Intrigued by the phenomenon, she proposes they investigate it together. As they spend the summer experimenting with the tunnel's power, Kaoru must grapple with what he is willing to sacrifice and confront Anzu's own hidden motives for seeking him out.
