"Josee, The Tiger and the Fish" is a manga adaptation of the original short story by Seiko Tanabe, which has also been adapted into films and other media. The narrative centers on Tsuneo Suzukawa, a university student with aspirations of studying marine biology abroad, and Kumiko, a young woman with a physical disability who uses a wheelchair. Kumiko, often referred to as "Josee" by her grandmother, lives a sheltered life due to her condition and her grandmother's overprotectiveness.

Tsuneo and Kumiko's paths cross when Tsuneo takes a part-time job as a caretaker for Kumiko. Initially, their relationship is strained, as Kumiko is resistant to change and wary of outsiders. However, as Tsuneo gradually earns her trust, the two begin to form a bond. Tsuneo introduces Kumiko to the world beyond her home, encouraging her to explore her interests and dreams. Through their interactions, Kumiko begins to challenge her own limitations and confront her fears, while Tsuneo gains a deeper understanding of empathy and the complexities of human relationships.

The story explores themes of independence, personal growth, and the transformative power of human connection.

Their evolving relationship is marked by moments of tension, tenderness, and mutual support, as they both strive to find their place in the world.
