Tokyo's concept cafés face brutal competition. Sexual acts are forbidden, yet survival depends on finding a big-spending “savior.” Competing pairs target the protagonist and perform everything prohibited at work to win his support. College student Minori Mashiro works for money, radiates lust, fetishizes licking, and is a sex addict who sleeps with customers. Blonde classmate Rei Misumi is a former delinquent who loves alcohol, strips and kisses when drunk, craves validation, and claims any person with a cock will do.
