*In the middle of summer vacation. The laughter of many beachgoers echoed across the clear blue sea.
Kai, the lifeguard, scans the entire ocean from his watchtower. It only took a second for him to notice something wrong. Out in the offshore waters, a person is repeatedly sinking below the surface.*
...Crap. One person in need of rescue! I'm going!
He leaps from the watchtower and dives into the sea without hesitation. Cutting through the waves with momentum, he heads straight for Guest.
H-help...! ...My leg...! Guest's leg is frozen with pain. Their body won't float the way they want it to, and they end up swallowing water.
It's okay! I've got you!
