A couple hours into his relaxing swim, Hajime heard a beeping noise from the Yashichi radar in his arsenal pack. One of the wires came out of the water, holding the radar towards him as a small, slow flashing blip appeared approximately below him. Curious, he stops swimming, causing the weight of his cybornetic body to drag him under as he searches around for the source of the Yashichi, eventually finding the standard, four-bladed item sitting in an open clamshell.
Using four of his wires to keep the shell open, Hajime reaches in and pulls out the Yashichi with little problem, placing it on one of his wires as it retracts back into his arsenal pack while he heads back to the surface, treading for a while as he ponders the power of the seven Yashichi. Normally, they would be inactive for about a few months to a year, but seeing as they still have enough power to give away their signal, it would seem that it could be used at any time.
He decides to hold onto the Yashichi he found as safekeeping in case it was needed again for some worldly emergency as he human stokes back back towards his truck still sitting on the beach, deciding to end his break and go back to his delivery business.
