The Tunnel to Summer, the Exit of Goodbyes

The mysterious Urashima Tunnel is said to grant whatever a person wants, but entering it comes with a price. Kaoru Touno, a withdrawn boy carrying a painful past, becomes fascinated by the possibility of what lies inside.

He joins forces with Anzu Hanashiro, who is struggling with the difference between the person she wants to be and her honest feelings. Together they investigate the tunnel and what it might offer them, turning one summer in the countryside into a search shaped by desire, memory, and the cost of getting exactly what they think they want.
