Title- A School Entrance Ceremony Without Incident
Keita is getting ready to go to his entrance ceremony when he brings up the fact that his parents are at work instead of going to his ceremony. As Ako tries to kiss him to comfort him, she is interrupted by Riko who tells her she should be more controlled since she is older, and during the argument Riko takes one of Keita's button without anyone noticing. At the entrance exam many of the guys comment that they applied for the school due to Riko and Ako going the school as well, Keita then overhears how the others are jealous that he gets all the affection from his sisters. In his homeroom Keita learns that his new teacher is Kiryuu Yuuzuki, the women from the western clothing store who took his measurements and seeing Keita in an erotic yet accidental pose. He also learns that Mizuni is in his class as well. As Keita is leaving his class, Riko shows up and scolding him for missing a button(which she took) and takes him to another room. Just as they leave Ako shows up looking for Keita and hurries after after learning Riko made her move first. Riko locks herself and Keita in a room and has a private moment together. As they leave they kiss once again in the hallway where they are discovered by Kiryuu who scolds them just as Ako finds them.
