While being treated by Kirino after getting his face wounded by some reason, Kyosuke reveals to her that he and Ruri decided to start dating, and much to his surprise, she does not complain about it. In their first date, Ruri wears a special cosplay she designed specially for the occasion, much to Kyosuke's astonishment. As the day pass, Ruri shows more about her tastes and preferances to Kyosuke and she reveals that it was written in a special guidebook made by her in order to attain her wish, which according to her is to have him and Kirino get on terms with each other. Despite not understanding the meaning behind her plans, he agrees to help her with it. The two then spends the following days hanging together in his and her houses, with Kyosuke being introduced to her younger sisters in the occasion, and by the end of summer break, they go to a festival together.

With Kyosuke unable to give her a straight answer, Ruri asks that he give her his response after the party the next day. Speaking with both Kirino and Manami, they both tell him to think over this decision carefully. During the party, Kyosuke thinks back on the past year after he began his life counselling with Kirino, whilst also taking an opportunity to tease her. After the party, Kyosuke agrees to go out with Ruri, officially making them a couple. As Kyosuke becomes stressed over how to act like a proper boyfriend, he brings Kouki along with him to the Games Research club, where the other members claim that they always knew Kyosuke and Ruri liked each other, and are surprised to learn that they decided to go out just recently. After being given some time alone, Ruri admits she has also been stressing about how to act in front of Kyosuke and simply asks that they go on a date.

After hearing no word from Ruri following their alleged break up, Kyosuke is shocked to learn from Sena that Ruri has transferred schools, later finding her house completely vacated. Troubled by this, Kyosuke comes to Kirino, who gives him his own life counselling and decides to help him search for her in a hot spring town. After they eventually manage to find her, Ruri points that Kirino hadn't truly accepted her dating Kyosuke, forcing her to confess her true feelings that she didn't want him to have a girlfriend, which was the reason she passed off Kouki as her boyfriend. Kirino states that despite this, she doesn't want to see her brother cry even more than that and wants to get the two back together to repay how much he has supported her over the past year.

Sent out to buy groceries by his mother, Kyousuke bumps into Manami at the supermarket. They get to talking, and they eventually arrange for Manami to come visit for the first time in ages.

A party is held for Kyosuke at his new apartment and Kirino arrives there just to find Manami, and despite her animosity towards her brother's classmate, she decides to put it aside for his sake. Ayase, Ruri, Saori and Kanako also attend the party, but chaos ensues when they start arguing about who among them should take care of Kyosuke as he prepares himself for the mock exams and Kirino settles it by appointing Ayase to the task. The mock exams come and thanks to Ayase's support, Kyosuke manages to earn an A grade and the right to return home. As he is preparing to move back, Ayase confesses her feelings for him, but he politely declines, revealing that he is already in love with someone else. Instead of kicking him like she usually does, Ayase kisses Kyosuke on his cheek and bids farewell to him.

Ever since the events of the previous episode, Kyousuke has been nervous about his improved relationship with his sister.

One day, Ayase calls Kyousuke out of the blue and asks him to see her. She wants to get Kirino a present, and wants him to think of what she would be happiest to get.

Concerned by how seemingly close Kyosuke and Kirino have gotten, their parents arrange for Kyosuke to live on his own so he can focus on his exams. With Kyosuke needing to earn an A grade before he can move back, Kirino adds that if he does succeed, she'll do any one thing he asks. Later, Kanako decides to pay Kyosuke a visit in his new apartment, proving awkward when she finds an eroge Kirino lent him. She proves smart enough to guess that Kirino is his sister, but is still oblivious to her being an otaku. The next day, Ayase visits Kyosuke to deliver a housewarming present, shortly followed by Ruri, leading to an awkward and embarrassing confrontation. After Ayase takes her leave, Kyosuke and Ruri reconfirm their stance on their relationship, with Kyosuke stating he won't start dating until he settles things with Kirino.

For years, ordinary high-schooler Kousaka Kyousuke has had an icy relationship with his younger sister Kirino, a star athlete who is also a star student.

Kyousuke comes home one day and is startled to find Kuroneko loitering in the living room by herself.

As Kirino organisings thing with school and friends following her return from America. Kyosuke grows concerned that she might start ignoring him again due to the way he forced her to come back, as well as struggling to find the meaning behind the kiss Ruri gave him when he went to retrieve her. Later, Kirino once again calls upon Kyosuke for life consultation, having him take her to Akihabara to watch a trailer for the next Meruru season before engaging in a long-missed shopping expidition she spent the entire night planning. As thanks for his help, and to celebrate a year of life consultation, Kirino gives one of her eroge purchases to Kyosuke to play.

Feeling frustrated that Kirino is ignoring her in favour of a popular mobile game called Love Touch that lets you exchange texts with virtual girls, Ayase asks Kyosuke to do something about it. After Kyosuke brings it up to Kirino, she gives him Love Touch to avoid being tempted by it, only for Kyosuke to end up becoming addicted himself. As Ayase becomes angered upon learning of this from Manami, Kyosuke attempts to explain how the game's heroine is similar to Ayase. He suggests imitating the heroine to better hold Kirino's interest, but this is soon met with violent backlash from Ayase when dubious phrases are brought up. After Ayase goes to Manami for advice, Kyosuke is shown the error of his ways when Ayase decides to imitate the game's yandere route in front of Kirino.

Kirino asks Kyosuke to pretend to be her boyfriend whilst they meet with a company director, Misaki Fujima. Misaki wants Kirino to work abroad as one of their exclusive models, forcing Kirino to have Kyosuke to act as her boyfriend as a reason not to leave. As such, they end up going on a 'date' together in order to keep up the act in case Misaki is spying on them, which proves more awkward when Manami sees them together. Whilst stopping at a place to eat, they encounter Kanako and her model acquaintance, Bridget Evans, and are forced to act in front of them too. Things become even more awkward when they encounter Ruri at the arcades. At the end of the day, Kirino becomes disappointed by Kyosuke's behaviour, saying she'll use a 'real boyfriend' next time. After Kyosuke clears things up with Ruri and hears her thoughts, he asks Kirino directly if she has a boyfriend, only to receive a cryptic response.

One day, Kirino's non-otaku, "public" friends—Aragaki Ayase and Kurusu Nanako—come over to visit. Kyousuke is harshly told by Kirino to not let her friends see him.

After hearing about Kyosuke and Ruri's breakup, Ayase becomes irritated that it had nothing to do with her. Nonetheless, she asks Kyosuke to take up his 'manager' role once more as she asked to help out at a Meruru concert that Kanako and Bridget are participating in. After hearing Kirino will be unable to attend the concert due to her work schedule, he borrows a bike from Kouki and rushes over to pick her up. After managing to get to the concert in time for ClariS to perform, Kirino feels thankful towards Kyosuke for his efforts.

Kirino has been acting strangely antsy for the past few days. The reason is that the little sister game she ordered hasn't arrived yet.
