Takarakuji de 40-oku Atatta ndakedo Isekai ni Ijuu Suru

After winning a 4 Billion Yen lottery, I quit my company job. But I ended up in a different world doing some serious volunteering, saving a poor village with contemporary Japanese materials and technology from the home center. What would happen if I bring modern home electrical appliances over there from Japan? And it seems I would fall in love with a beautiful girl in the village.
