A man finds himself in an unknown city. He had no doubt that he was in Tokyo, but the scenery before was strange. Streets littered with wooden structures and barracks, no tall buildings and the wide sky visible in sight. The only vehicles on the road are classic cars.

The only thing in his bag is his smartphone, which doesn’t have any internet to connect to. Can this time-traveling old man who has lost everything———– clothing, food and shelter———– survive?
