Ride Your Wave

Upon entering university, Hinako moves to a coastal town. She loves surfing, and when she's on the waves she's fearless, but still feels uncertain about her future. When a fire wreaks havoc in the town, Hinako encounters the young firefighter Minato. As they surf and spend more time together, Hinako feels drawn to someone like Minato who devotes himself to helping other people. Hinako also holds a special place in Minato's heart, and when he suddenly drowns while out surfing alone, he comes back to her as a ghost trapped in water. As everyone else gets over Minato's death and tries to move on, Hinako comes to depend on his spirit.
