In a small town nestled in the mountains, there is a hot spring inn where Rio works as a party companion. "I love alcohol, but I get drunk so easily..." With her erotic and adorable character, she stirs up scandalous trouble throughout the inn. "Oh no,客人, you can't do that!" Overwhelmed by the alcohol and pressure, she surrenders fiercely. In the outdoor bath, they playfully wash each other, engage in rock-paper-scissors with a feast of women's bodies, this place is a paradise of men's dreams.
