1一年之初

A euphoric moment of Haruka securing Chiaki's kimono gives way to frustration that Kana is oversleeping along with the consequent compensatory frenzy thereof that does not seem to bother Uchida who (at the cost of her micro-economy) has been enjoying herself at the festival. The fortune that Uchida purchases with Kana's money only amplifies this fact; unfortunately, Uchida takes the fortune too seriously and overlooks that realizing a fortune takes effort on her part. The next arc features Chiaki contrasting fried noodles and their instant-cup brethern with Touma who has no idea what Chiaki is telling her until Haruka returns home with Kana and prepares some tea that Takeru enjoys using old leaves rather than the ones from the first harvest. The arc that follows thereafter details the home visit the school nurse regarding Chiaki who is none too thrilled with the prospect and that Haruka refuses to intercede as Chiaki's guardian. Between Takeru's obliviousness and the school nurse's flirting along with Kana watching the whole thing, poor Chiaki is absolutely mortified. The final arc details Takeru availing a superstition that points to Kana pulling her usual pranks and a fact that has been demonstrated all throughout.

2我也要

Touma pays the Minami sisters a visit with an unknown payload whose revelation Chiaki objects in Haruka's absence. Though she inhibits herself for the time being, Kana begins to succumb to avarice when Fujioka comes for a visit. What follows is an exercise in game theory in which Kana leads Chiaki through an enigmatic scenario to obfuscate her volition for having the entire payload to herself since Haruka's estimated arrival time is an unknown variable. Kana's only mistake is that she forgets to consider all the players. The next arc features Haruka and Chiaki being rather vague and indirect about the supermarket and the route thereof as well as a neighborhood dog giving way to Chiaki encountering a shopping list that she suspects that Kana tampered with. The arc thereafter details Hayami comparing notes with Maki regarding Hosaka before she gets the idea to wield Hosaka's computations as her plaything. Hosaka tries befriending Maki and Atsuko but is puzzled when they swiftly flee. The final arc features Haruka taking notes from a cooking show about the preparation of curry while detecting the necessity of visiting the supermarket. Chiaki taking on this stewardship with the very notes that Haruka was taking earlier ends up inspiring Hosaka and herself an extra spicy curry.

3吵架了

Touma's ecstasy during the homebound commute is quickly extinguished by Natsuki helping himself to the snack consecrated for that purpose. Thereafter, Touma's sudden arrival on Chiaki's doorstep gives way to the revelation that Touma has an ongoing passive-aggressive dynamic with her brothers and paints a dysphoric snapshot of Touma's family. The next arc details how the Minami sisters deal with an abundance of apples. The arc concludes with the Minami brothers prosecuting protracted and complex computations regarding the utilization of the apple Touma brought back with her. The arc that follows thereafter details Haruka conferring culinary counsel upon Natsuki while Kana and Chiaki discuss Haruka and Natsuki first as individuals and then as a romantic couple. Chiaki dismisses the prospect before directing Kana to finish the curry Haruka is making. Unfortunately, the culinary protocols for both Haruka's curry and Natsuki's cookies get interchanged with dysphoric consequences. The final arc is related to the first and details the conflagration of Touma confronting Natsuki who repels his brothers' attempts to come to their sister's aid. In an attempt to guide her through guarding against this kind of misunderstanding, Kana demonstrates to Touma a form of Japanese script that looks a lot like arithmetic.

4应有的秩序

In spite of being the reason for Touma's earlier »Hands off!!!« repulsion, Kana decides that Touma is getting out of hand while making the same mistake with Chiaki at dinner. Haruka swiftly answers the dominance question between Kana and Chiaki right before Touma arrives again with a slideshow of her family government. Kana gives Touma a photograph to show Natsuki that causes a computation crash. The next arc depicts the Minami brothers discussing what to give Touma for her birthday and revealing that Natsuki is the second-generation Banchou that has gotten into a misunderstanding with one of his classmates Hitomi who is fishing for insight regarding maturity and thinks that she can determine Natsuki's thoughts via eye contact.

5变得有趣

Chiaki is down in the dumps at the upcoming stewardship of the pool and decides to enliven things by challenging everybody to a game of tag with the »it« person having the garden hose. Makoto stealing the hose and Chiaki's retaliation sparks a three-way water fight with Uchida and Yoshino that obfuscates the issue of Chiaki not being able to swim and that the compensatory computation thereof backfiring on Chiaki. The next arc is a snapshot of Kana's computations of the intermediate school social ambiance in terms of a outing to a public pool followed by the computation crash wrought upon Fujioka regarding appropriate male contact with females and the aftermath thereof. Touma demonstrates her perspective on the issue only to find that male-to-male contact is much more straightforward and has greater latitude.

6就此别提了

A euphoric beach outing having the dysphoric prologue of Kana being carsick is reflected upon warmly by Uchida and Yoshino who have taken the whole experience in stride. Yoshino remarks that Chiaki has become attached to Fujioka as an elder sibling in much the same way that Kana has with Uchida and her. Chiaki's exhortation for the whereabouts of her teddy bear disrupts the reminiscence; fortunately, Fujioka brings it back and Kana successfully obfuscates her role. Maki tempers her disdain for her summer homework by successfully wielding Fujioka's computations as her plaything until Kana and Chiaki extinguish her machinations. The next arc features Uchida having a near-complete computation crash as she struggles to complete her summer homework without Chiaki's counsel as the penance for abusing Chiaki's goodwill. Fortunately, Chiaki is not heartless; she eventually relents after seeing Uchida and Makoto's demonstration of interdependence being a two-way street. The final arc features Kana's attempts to forestall the approaching autumn backfiring upon her as Chiaki, galvanized by all the pranks Kana played on her, retaliates by eating Kana's dinner in addition to her own.

7要是我可以的话

Frustrated and bored with the practice for the three-legged race, Chiaki decides to call it a day much to Makoto's dismay. Kana tells Makoto of Chiaki's dearth of sports proficiency and warns that helping Chiaki will jeopardize his transvestite mirage. It becomes obvious that Makoto and Chiaki have not learned to synchronize with each other and that Makoto's transvestite mirage is quite the Damocles sword for Kana to maintain as is demonstrated when a mishap with soda leads to Kana and Chiaki sparring with parables that teach a physical metamorphosis is not a prerequisite for a euphoric relationship. Chiaki accidentally breaking the Minami sisters' mugs sets the stage for a labyrinth of complex and unnecessary strategic game theory computations that conclude to Kana's detriment.

8这就是法则

During the homebound commute, Uchida and Yoshino's stopover to buy some baked yams during the homebound commute gives way to Kana explaining to them her »Laws of Popularity«. Availing a bunch of soda cans, Kana directs Uchida and Yoshino through an exercise with soda cans to practice the Law of Weakness Appeal. Unfortunately, Chiaki (especially after the soda geyser) is not amused at the exhibition and Atsuko is put on the hot seat after Haruka takes Maki away. Touma imparting an emphatic »Watch where you are going!!!« punch to a contrite Makoto before walking away ultimately demonstrates that male-female interaction is as a kaleidoscope and that there are a myriad of variables in play. While Kana spends the next arc fishing for iconoclastic responses, Atsuko shares her »cool when silent« perspective of Hosaka before later comparing notes with Maki leads into a comical social sequence in which Hayami and the approaching Hosaka along with Maki and Atsuko seem to have completed these cerebral computations without verifying the results with the outside world.

9是吗？

During a lazy afternoon, Kana decides to help herself to some oranges while Touma and Chiaki read at the kotatsu before getting the idea to snack on an orange. It is not long before Makoto and Uchida learn the root cause: Kana delivering a preemptory »Hands off my oranges; go get your own!!!« karate chop to both Chiaki and Touma. Another arc has everybody galvanized by the Yuletime ambiance: Chiaki synthesizing a huge stocking and leaving it to chance what present she receives, Touma learning to appreciate »useless/annoying« family rituals, and Hosaka acquiring a part-time job as a cake salesman dressed in a Santa Claus suit even though he does not encounter Haruka by that avenue as per his daydream. Haruka hosts a Yuletime banquet at her house.

10对于态度

Caught up in a sudden rainstorm, Touma is forced to make an emergency stopover at Chiaki's house but finds that the hospitality comes with a price: Chiaki refusing to lend Touma any clothes due to her abrasive conduct. Though she initially misinterprets Natsuki's counsel on her conduct, Touma finally catches the lesson -- and a set of clean clothes. The next arc features Chiaki's lack of discretion and foresight with her affinity for trivia and facts. Fortunately, Fujioka helps Chiaki put her error in this area into perspective. The arc that follows thereafter details the prologue of the social dynamic Fujioka is involved in with both Chiaki and Touma: Chiaki mortifying Touma out of Fujioka's lap. The arc after that details that Natsuki has the same problem of abrasive conduct about which he earlier lectured Touma who enters the room and seats herself at the table. However, Natsuki's attempts to heed his brothers' counsel along with Touma's opinions of the Minami sisters sour the ambiance.
