Yua, who is active in the cheerleading club, headed to practice that day as well. But suddenly, she found herself enveloped in light and transported to another world. Confused and terrified, Yua had no idea what was happening. The one who extended a helping hand to her was Chihiro, who had also been transported to this world several years ago. She had adapted to this world and now ran a tavern called "Night Owl Kitten". However, the tavern was essentially a brothel... Yua started seeking help to return to her original world through "enkou", but as she interacted physically and verbally with the people of this world, sometimes negotiating, she found herself deeply involved in "enkou". Pleasures she couldn't have known from just doing club activities, and a sense of fulfillment from being needed. Will Yua be able to return to her original world? [Translated from the official site]
