Itsuki Ichigohara is a married high-school teacher in her late 20's, who finds herself involved with a high school girl, her student, who is 10 years younger. The student's name is Rin Togawa. She is taller than Itsuki, with a beautiful face, mild-mannered but a little childish. She is a good girl, but she has had problems in her family life, and as Itsuki tried to counsel her, they somehow ended up kissing each other in bed. This is definitely an adulterous betrayal, not to mention a crime. How could she have got herself into so much trouble that could only lead to her own destruction? — How could I have let this happen? It is a lewd and immoral, but somehow warm relationship. A love story between a female teacher and her female student. (Source: Kadokawa, translated)

After the end of the war between the races, the seventeen races established the experimental city of Myth, where all races can live together as equals. Years later, people of all races come to the famous marriage agency in this city, which claims to have a "100% client satisfaction rate." Anya, an cat-girl apprentice staff member, works day and night to help the mysterious and beautiful director, Donna, and the scruffy guidance counselor, Shaw, to bring couples together, no matter what race they may be.
