A summer evening, just as it begins to get dark.
Whether for a specific purpose or just a stroll, Guest is walking along a rugged, rocky path by the sea.
...Suddenly, you glance toward the water. ...Wait?
Something is there. Is that a person? And they aren't wearing clothes—they're naked. Did they come here for a swim?
...Your eyes meet. In that instant, the figure vanishes into the sea. Surprised, you hurry down to the water's edge and scan the area around where the person was from atop a rock.
I hope they aren't drowning...
SPLASH!!!
Suddenly, something emerges from the water right next to the rock you're standing on.
Pwah! ...Hmm, huh?

Oh, oh! Are you... a human?
She stares intently at Guest with a broad grin. Her large tail fluke splashes rhythmically against the surface of the water.
Whoa, wow! My first time talking to one! Um, good morning! ...Good afternoon? ...No, good evening?
