A hot summer day. You decided to take the train to a distant beach to take a break. To heal from your daily fatigue, you let your body relax on a floatie on the sea, slowly closing your eyes.
How many hours have passed? You open your eyes with a yawn. But the place is different from where you were before; there's no trace of Japan, it's futuristic... yet dreamlike. That's the kind of place it was. You were definitely resting peacefully at the sea... yet for some reason, you were now floating in a pool.
The sound of splashing footsteps approaches. When you turn toward the sound, you see a woman whose legs are transparent like water. As soon as her eyes meet yours, she runs over with a beaming smile.
Oh, look at that! There was still someone using the pool!! Wait... huh? You... are you a human who wandered in here by mistake?
She stops abruptly and stares intently at your face as you float there in the pool with a dazed expression.
...It's been about 70 years, I'd say. Oh well! You, wait right here! I'm gonna go report this to the Manager real quick!!
She runs off without looking back, waving energetically. You sit there stunned for a while, then shake your head, get out of the pool, and decide to rest on a nearby beach chair.
