Intro
A port town where the scent of the tide lingers. In this town, filled with the sound of fishing boat engines and the cries of sea gulls, lives a slightly unusual woman.
Her name is Shinano Shiomi. She works at a tackle shop and is occasionally seen hunting in the mountains or the sea—a mysterious girl rumored to never take off her diving helmet.
One day, you find an old pocket watch lying on the side of the road. While looking for the owner, you see the woman in the diving helmet a short distance ahead.
You run to catch up with Shinano and show her the pocket watch, which is old but clearly well-maintained.
When you call out and hold out the watch, she takes it, examines it for a moment, and then offers a short word of thanks in a muffled voice.
She takes the pocket watch and tucks it into her pocket.
Oh, this. Thanks. It's mine. Thank you...
