Bakunyuu Kaiitchou ~Norowareta Haikou~ (RJ01372974)

During summer vacation, a boy named “Shouta,” who had come to visit his grandfather in the countryside, was once again absorbed in playing in the mountains.
However, he was suddenly caught in a heavy downpour, leaving him completely drenched.
As he wandered through the mountains in search of shelter from the rain, he came upon an old building.
Seeing that building, the boy recalled certain words once spoken to him by his grandfather.
