Kyosuke asks for advice from his father, who helps him by giving the full story on those reports. Although Ayase still refuses to make up with Kirino after Kyosuke reveals the truth behind the news story, Kirino gains the courage to stand up to her and expresses her love for both her friends and eroge.

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 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.

After their pictures are taken, the girls learn Mio had turned down a recommendation for a university because she wanted to study together with everyone.

After a successful play, the girls apologize to Azusa for making her worry and decide to hold an overnight practice session at school. Later that night, they browse through the closed stalls, where they find the missing gravestone, and give their thanks to the occult club.

After not being impressed with having other girls train for them, Ritsu and Mio decide to have a cram session. While doing impersonations of each other if they switched roles, they find the key to successfully acting out their parts. Noticing Mio still lacks confidence, Tsumugi arranges for her and the others to work as maids in a high-end cafe to help get over her embarrassment. Although she gains some confidence, Mio insists it is different from being on stage. Meanwhile, Azusa grows concerned that, with everyone rehearsing for the play, no one is preparing for the live concert.

“No Club Room!” “Bushitsu ga Nai!” (部室がない!)

The club room is closed for repairs, leaving the girls nowhere for practice. While trying to find a suitable location for their practicing, the girls try to come up with lyrics for the song Tsumugi wrote. Failing to find anywhere in the school to practice, they rent out a studio, but end up wasting time discussing lyrics and run out of time before they can practice, though the club room reopens the next day. The following night, Ui helps Yui write some lyrics, but ends up catching a cold, leaving Yui, who has always relied on her, to look after her instead.

The next day, Azusa runs into Yui in the club room hoping to practice, but ends up cleaning Ton’s tank and helping her with understanding how to play the song Tsumugi composed, as she cannot read sheet music. Yui reminds Azusa that she is who she is, and personalizes her keychain.
