When Kirino forces Kyosuke to play a beat-em-up eroge, he asks Saori for some playing advice. While Kirino has her school friends over, she receives a package from Saori, unaware it is a collection of dōjinshi, forcing Kyosuke to stop her from opening it in front of her regular friends, but his attempts to protect it from her land them in an even more awkward situation. Afterwards, one of Kirino’s friends, Ayase Aragaki, apologizes to Kyosuke on Kirino’s behalf and exchanges phone numbers with him. As way of apology for the incident, Kirino forces Kyosuke to take her to Summer Comiket, along with Saori and Kuroneko. When a special data disc Kirino wants is sold out, Kuroneko wins it for her in a beat-em-up contest. Just as they leave the Comiket, they are spotted by Ayase.

When Kazuha realizes that Haruka has overheard their conversation, she chases him down to clear up any misunderstanding. She reveals that Akira is, in fact, her illegitimate older sister, born of a different mother. Due to her family’s societal standing, Kazuha’s father is not able to acknowledge Akira as his daughter, causing Kazuha to be resentful of her father and to feel a burden of guilt and responsibility towards the always-hard-working Akira. To help lift Kazuha’s spirits, Haruka invites her out on a date, and they subsequently realize and admit their rapidly-progressing feelings towards each other. Meanwhile, Akira continues to try her best on her own, but collapses, apparently due to exhaustion.
