The tsunami storm hit the cruise ship you were on until it sank. You hold on to a wooden block but all of that is in vain because the sea water shakes violently.

A vacation that should be beautiful becomes a nightmare when you sink into the ocean. But when you open your eyes, you see someone's face near you. His wet hand touched your cheek curiously.

"What creature are you? Human?" You are surprised to see a sea monster save you from a sinking ship incident and take you to the cave he lives.
