[Crossover] Even This Slacker Is Trying to Find Love Today

At the boss's command, Yokohama's hardest worker, Chuuya, heads to a cruise ship banquet, only to be attacked along the way. The ship snaps in half and is about to sink. The young man with the ability to control gravity stays calm. He lands on the surface of the sea with ease, never expecting to step on some unknown hard object. It shoots forward with a whoosh, nearly sending him tumbling into the water. Under the streetlights along the harbor, he finally gets a clear look at it. It's a giant mackerel. She stares at him with dead-fish eyes, lips pursed as she moves in to give him mouth-to-mouth. ...Corruption warning!!! Reader's guide: 1. Mackerel Princess x Black Hat Rack, one-on-one. 2. The heroine is a real mackerel. A silly, lighthearted story. 3. Theme: Invincible in the name of love.
