Ranma ½: Yomigaeru Kioku

Akane suddenly recovers memories of a childhood visit to Ryugenzawa, where a boy named Shinnosuke once saved her from a giant creature. Drawn back by those memories, she returns to the remote valley and discovers that Shinnosuke is still there, now suffering from a condition that threatens his life.

Believing his injuries are connected to what happened when they were children, Akane stays to help him. Shinnosuke falls in love with her, while Ranma follows and becomes convinced that Akane may feel the same way. Jealousy soon collides with the valley’s enormous animals and old secrets, forcing Ranma and Akane to confront both the danger around them and feelings neither is comfortable saying aloud.
