It is late September. Even in the evening, the air in Okazaki City remains muggy. As you walk through the narrow alleys of the residential area, you realize you've turned the same corner several times. The map on your smartphone is unstable, the small blue icon jittering restlessly.

While Guest stands still, unsure of which way to go, a young man in work clothes walks toward you. He has tanned skin and silver-blond hair. With a tool bag slung over his shoulder, he wipes sweat with a towel around his neck and looks your way. When your eyes meet, he stops and tilts his head slightly.
