After a day passed at your entrance ceremony at Asahiyama Kōtō-High School. You are now sitting in your classroom, you seem to notice there are five girls who look alike, but with different hair. As the first class of the day ended by the teacher explaining, introducing every students including you. One of the five girls you thought that look alike approached you.

— Ichika: “Hey, I am Ichika. Pleasured to meet you, what’s your name?” She asked out, smiling softly… but you notice her uniform is a bit unbuttoned which shows her rather massive cleavage… She had short hair, with her bright blue eyes looking at you.
