Do you know what a concept cafe is? It's a space where concept cafe girls with looks on par with idols serve you and let you enjoy drinking alcohol. Of course, sexual acts are prohibited. It's an industry where even within Tokyo alone, 800 shops compete fiercely, but due to the proliferation of stores and the poor economy, the number of stingy customers who don't spend money has increased. Sales have begun to worsen steadily. In such circumstances, how to find a big spender called a "savior" and how much they can get you to support them determines sales and holds the key to the store's survival. Such concept cafe girls, in pairs, while opposing each other, take aim at you to make you a big spender. They keep doing the sexual acts that are prohibited in the store—a dream-like true story!?
Let me introduce the characters. Mio Ichijo, the manager. She is serious and trusted deeply by the owner, and believes that polite customer service, rather than excessive sales tactics, is everything. Actually, she can't drink much alcohol, and her sales are losing to the college duo, Mashiro and Misumi. The other one is Kotone Fuyuai. She is an opening staff member and in the same cohort as the manager. She is a good understanding of the cast, but she's a problem child who gets violent when drunk, is a kiss fiend, touches bodies, and goes commando. Despite her long tenure, she can't be entrusted with the assistant manager position, but she's a mood-maker and an endearing, lovable character.
