As Ruri and Sena’s game is bashed on the internet, they decide to work harder towards making a better game. As Kyosuke prepares to go home, he receives a text from Kirino telling him to throw away her collection of eroge and anime goods. Kyosuke contacts Ayase, who reveals Kirino hasn’t been in contact with her since she left either. Kyosuke then meets up with Ruri, who reveals her heartfelt thanks for helping her fit into school and encourages Kyosuke to fly to America to find the root of Kirino’s problem, giving him a kiss on the cheek as he goes. Arriving in Los Angeles, Kyosuke meets up with Kirino at her track camp and plays eroge with her, cheering her up as she hasn’t had time to play her collection. Kirino reveals that she had wanted to challenge herself and be more independent, saying she wouldn’t contact anyone until she managed to beat someone in a time trial, which she hasn’t been able to do. Kyosuke tells Kirino that he is lonely without her and asks her to come back to Japan, which encourages Kirino to beat her elementary school roommate in a race and go home with him, reuniting with her friends and her anime.

Ruri and Sena are asked to work together to create a game for an online contest, with Kyosuke supervising them. After thinking about his options, Kyosuke suggests that they make an eroge. As the girls pitch their concepts, Ruri comes up with an expansive novel-based game, mentioning how she wants to do it in order to show Kirino up. Sena then gets upset when her concept is rejected due to its explicit Hardcore Yaoi themes and stops coming to the club, leaving Kyosuke and Ruri to work on their game alone. Just as Kyosuke and Ruri start to warm up to each other, several bugs show up in the game’s code which the club can’t fixed in time for the contest’s deadline, so Ruri begs Sena to help her out, realising it’s okay to lean on others sometimes. Working together, they manage to finish the game, which ends up winning the “Worst Game Award”.

As Kuroneko, whose real name is revealed to be Ruri Goko, enrolls in Kyosuke’s school, Saori feels a bit downhearted that she hasn’t heard from Kirino. Kyosuke notices that Ruri is having trouble making friends due to her personality. Kyosuke and Ruri decide to take a look at the Games Research club, which is run by Gennosuke Miura, the guy Kyosuke had borrowed the bike from, and they eventually decide to join. As Kyosuke and Manami try their best to help Ruri, Ruri accuses Kyosuke of treating her like a replacement for Kirino. A welcoming party is held at the club, where Kyosuke meets Kōhei’s younger sister, Sena Akagi, who goes a little crazy when her obsession with yaoi is revealed and she accidentally reveals her perverted fantasies to the rest of the club, forcing Kyosuke to call up Kōhei to calm her down. At the end of the day, Kyosuke admits that, despite feeling lonely without Kirino, he won’t stop helping out Ruri, which makes her feel a bit happier.

One morning, Kyosuke is surprised to find Kirino behaving politely to him. That evening, while Kyosuke worries about whether she is forcing an act in front of everyone, Kirino uses her final life counseling session to ask Kyosuke to buy her an eroge that is launching at midnight in Akihabara. As Kyosuke gets in line, he runs into his classmate, Kouhei Akagi, who is buying a yaoi eroge for his own sister. Meanwhile, Kuroneko calls Kirino about the cat ears she is making for her and also tells Kirino that she might be going to change “her way of calling” Kyosuke. Kyousuke, after realizing that the trains are no longer running, manages to convince one of the other customers to lend him his bike so he can ride back home. After Kyosuke gets back home with the game, Kirino asks him to play with her. She then shows him all of the medals and report cards with bad grades she had received throughout the years. The next morning, Kyosuke learns that Kirino has left home for America for track and field training, leaving him to wonder about the night before and why she never told him about her departure. In the beginning of the new school term, Kyosuke meets up with Kuroneko, who would be attending his school as his underclassman.

Kozue runs away in shock at the sight of the twins making love, while Nao calmly left the scene, but Sora wouldn’t even care. Haruka thinks of ditching school, but she tells him to think little of it. Kozue tells him the next day that she’ll never talk to him again, while Nao effectively ends her relationship with him after his apology. That night Haruka fights with Sora when he tells her that they stop doing it, even inadvertently hitting her. Things get complicated when they find out that their parents left no money for the two, and in order to survive they have to be taken under custody of their relatives, but this means them living apart. That afternoon Haruka awakens to find Sora missing and her room in a mess. He goes looking for her after receiving a text from Sora which sounds like a suicide note. Nao even helps him in looking for her everywhere, mentioning to him about her confrontation with Sora, saying she has seen the two making love that summer day, and that “now they are even.” Haruka then remembered the lake Akira mentioned the other day. Haruka finds Sora, and his attempt to stop her from going deeper in to the lake nearly ends in them drowning. Days later the two leave the place to live together overseas in the city where an artisan who had connection with their parents lived, hoping to find happiness elsewhere. Though Kozue disagrees, Nao believes they will do just fine.

One morning, Kyosuke is surprised to find Kirino behaving politely to him. That evening, while Kyosuke worries about whether she is forcing an act in front of everyone, Kirino uses her final life counseling session to ask Kyosuke to buy her an eroge that is launching at midnight in Akihabara. As Kyosuke gets in line, he runs into his classmate, Kouhei Akagi, who is buying a yaoi eroge for his own sister. Meanwhile, Kuroneko calls Kirino about the cat ears she is making for her and also tells Kirino that she might be going to change “her way of calling” Kyosuke. After Kyosuke gets back home with the game, Kirino asks him to play with her. Later that night, Kyosuke learns that Kirino plans to leave home for America in the morning for track and field training, which disappoints him since she never told him about it before. Kirino becomes enraged when Kyosuke does not show the behavior she expected of him and beats him up. The next morning, Kirino decides not to go, and later also announces to Kyosuke her life counseling is not over yet, which makes Kyosuke happy.

Haruka takes Nao on a date again, but he cannot shake the sight of Sora masturbating that night off from his mind. Eventually Haruka hits his limit and tries to get rid of those thoughts by taking Nao to a hotel, but she rejects his act and asks if he really loves her. Haruka is unable to answer and returns home. Soon after, Sora gets a fever and Haruka stays home to take care of her. That evening, Sora, with her fever subsided, confesses her feelings to Haruka and the two make love, beginning a relationship. This did not go unnoticed, as everyone, especially Kozue and Nao, begins to see the twins spend more and more time with each other. One afternoon, when Kozue and Nao decide to visit the Kasugano residence, they catch the twins in the middle of making love.

俺の妹がこんなにメイドなわけがない “Ore no Imōto ga Konna ni Meido na Wake ga Nai” “My Little Sister Can’t Be This Maid”

After running into her at the supermarket, Kyosuke invites Manami over to his house to help him make lunch. However, Kirino isn’t too pleased with having Manami around and makes various plans to hamper her visit, ranging from giving her arduous tasks to laying embarrassing pornographic traps in Kyosuke’s room. Later, Saori holds a “personal harem party” for Kyosuke with Kirino, Kuroneko and herself dressed as maids. There, Kuroneko shows off a perverted manga with characters based on Kirino and Kyosuke, and later even starts calling him “nii-san” much to the ire of Kirino. Kyosuke has a small outburst at Kirino for her behavior, until she gives him a present, saying she is grateful for all his help.

This episode replays to the event where Haruka is trying to talk to Sora about his relationship with Nao, but this time Sora is always at the back of his mind, since, lately, she seems not to accept Nao, and that she seems to be teasing him. Haruka suggests a date with Nao, but cannot get to tell Sora about it, even disguising it as if he will be spending time with Ryouhei. During the date, though, Nao notices that Sora is never far from Haruka’s mind, him buying things for his sister rather than for her, and eventually spoiling their date. They plan to make croquette curry upon arriving home, but is canceled when Haruka finds Sora not feeling well in her room after having a bad dream. The next day Nao notices that Haruka tries to hide his date with her from Sora, but she just went along. One night, Haruka catches Sora masturbating in her room while mentioning his name, much to his dismay—she is enamored with him ever since that one summer day in their childhood when Haruka kissed Sora while playing.
