Josee to Tora to Sakana-tachi

University student Tsuneo Suzukawa works several jobs to fund his dream of studying marine biology abroad and spends whatever time remains diving. His plans take an unexpected turn when he meets Kumiko, a sharp-tongued young woman who uses a wheelchair and insists on being called Josee. Her grandmother offers him paid work assisting her, and Tsuneo accepts because it seems like one more way to save money.

Josee has grown used to a very small world shaped by her grandmother's fears, but she desperately wants to see the places she has only imagined. When Tsuneo begins taking her outside, their abrasive arrangement slowly becomes a partnership that opens each of them to the other's world. As their ambitions begin colliding with reality, both must decide whether the fear of being hurt is worth surrendering the future they truly want.
