Waka-sama no Zasuru Sekai

After inheriting his grandfather's Shinto shrine, the orphaned Umezono Ryouga accidentally summons and unseals a goddess who nearly devours him. He escapes by offering to cook and buy her delicious food with his meager part-time job earnings. Curious about the modern world, the goddess Waka-sama ventures out with Ryouga to search for her sister, encountering new cuisines, sights, spirits, monsters, and gods along the way.
