Seki seems to be diligently studying, but instead he is writing his signature on his ruler although it looks more like a brand logo. Rumi made a cutesy signature back when she was younger and attempts to recreate it on a nearby piece if paper. Seki's ruler isn't the only thing with signature as he has signed: his bag, a book, and his desk and then he begins to 'brand' every single part of his mechanical pencil, although struggles with the lead, so marks out the Seki logo on a bunch of them using white-out. With everything he owns (and doesn’t) now emblazoned with his logo, Seki draws it on the window, so when he looks at the sun (via protective film), that too is now branded. His fun is then interrupted when teacher asks everyone to hand their homework which flusters Seki, much to Rumi's amusement, but Karma catches up with her quick as her recreation of her signature was on the homework sheet.

Seki has brought a log and a small Japanese Rhinoceros beetle which he takes good care of until a larger Stag beetle comes out. The Rhinoceros beetle beats the Stag beetle, which is revealed to be a fake that was controlled by Seki. Then Seki brings out a Hercules beetle, which is even larger then the previous Stag beetle, but the small Rhinoceros beetle swiftly defeats his larger opponent who explodes from the killing blow. While seeing the Rhinoceros beetle win is great, Rumi quickly realises that these false victories will hinder the beetle in the real world and Seki is setting up for failure. Seki brings out the next challenger, a giant Rhinoceros beetle found only in fiction, which the real life Rhinoceros beetle flies away from, leaving Seki to search for it outside of lessons.

Seki has got a pile of small plushies on his desk as well as a crane with a claw on the end and he intends to simulate a claw-crane game machine seen at arcades. Rumi isn't interested in watching until she notices one of the plushies has a head of a panda and presumes it to be from "Drama Panda", a popular plushie line that features a panda with a cool face (his faces comprises of his eyes and nose) making exaggerated poses. Rumi has the complete collection of "Drama Panda", but the poses that this one is making is not one she has seen before, so pays Seki to operate the claw machine to get it as who knows when she will see this one again. After 4 attempts, Seki finally gets the panda that Rumi wanted, however the panda is not a "Drama Panda", but a "Great Gag Panda" and Rumi throws the panda back at Seki's desk like a spoiled brat as she doesn't want fakes.

It is Art and the main activity for the lesson is drawing portraits. As looking at each other can be awkward, the class is split into group of threes so instead you have someone looking at you from the corner of your eye. Our group has Seki, Goto, and Rumi, with Seki sketching Goto, Goto, sketching Rumi, and Rumi sketching Seki, although it is bold to say Seki is sketching as he is too busy playing with a ball labyrinth game and the ball in this game is actually a tiny egg, painted to look like a chick. Rumi orders him to start drawing Goto (for her sake) and he does, after sharpening his pencil a lot. Goto is also struggling with her portrait as Rumi keeps on switching facial expressions and that she is interrupting their alone time as a couple, but she will try to capture the maiden in love that is Rumi. Seki draws Goto, or more specifically her braid, which he has turned into a maze and he moves the egg through it by bending the page. Once that maze is clear, the egg falls to the floor and onto the pencil shavings which have been arranged to make another maze. Seki then tackles this maze, moving the egg with his foot, but once that maze is cleared Rumi takes the egg into her possession and threatens to destroy it if Seki doesn't draw Goto properly. Seki then quickly draws a portrait of Goto and it is satisfactory for Rumi, in a 'C grade performance from an A grade student' kind of way. With Goto now properly drawn, Rumi hands him back the egg although to Goto, it looks like some form of couple-only currency and Seki has been rewarded. The lesson is almost over, so the teacher gets everyone to stop drawing so they can look at what people have done and they are particularly impressed at Goto's work. She has drawn Rumi with a myriad of expressions, which is only possible with love and not the fact that Rumi had every single one of those expressions when dealing with Seki.

It's Sports day and Seki's and Rumi’s team are participating in the ball toss: a game where you toss balls into baskets which are high upon some poles for a limited amount of time and the team who has the most balls in the baskets wins. Under one of the baskets is a wasp nest and Rumi takes note and care not to hit the nest and send an angry swarm to attack her peers, however, Seki is in no thoughtful mood as he is trying to hit the nest. Rumi tries to stop him and does so by getting Maeda to be in front of Seki, preventing him hitting the nest. Time is up and the nest remains un-hit until Uzawa throws one last ball and hits the nest, causing it to fall by Rumi's feet, who then inspects the nest after no wasps pour out. The nest is fake and inside is a small pot of honey, which she takes for herself and annoys Seki in the process as he lost his own game.

Later on in Sports day, Seki is painting his nails with red paint. The reason as to why comes after the tug-of-war event that he competed in, where his nails look like they have been damaged enough to start bleeding due to the effort he 'exerted' to help his team (btw they lost) and once he is satisfied with performance, he washes his nails clean. The next fake wound is on his feet as after 100m relay, where he takes off his shoe to reveal a bloodied sock and his final injury is bloodied hands after his gloves 'gave way' when handling the giant balls needed for the giant ball roll, an event he is not competing in, but instead helping to set up.

Seki has got out a deck of 100 poet cards or Uta-garuta which are used to play Karuta. Karuta is a traditional Japanese card game for 2 players where each card either contains the full 5 verses (Yomifuda) or the last 2 verses (Torifuda) of a Hyakunin Isshu poem and when a 5 verse is read out, players race to remove the card with the same final 2 verses from the field of play. The aim is to remove all cards from your side of the field (or the field depending on the game) and if you successfully remove one from your opponent’s side of the field, you place one of your cards to your opponent’s side. Seki has also got a deck of Flower cards or Hanafuda which comprises of 48 cards of 12 suits which correspond with a month of the year and is used to play a variety of games similar to the west's 52 deck of cards. However, Seki is playing a game more similar to modern TCGs (that said, Yu-Gi-Oh! does have an archetype based around Hanafuda cards, known as Flower Cardian) and Uta-garuta has lost the round, but wins the next round. The Hanafuda win the next round, but lose the next one and both decks are eventually swapped out for Tarot Cards (these cards also serve as the basis for a Yu-Gi-Oh! archetype called Arcana Force).

Seki has got a small Christmas tree out on his desk and Rumi isn't too opposed to it, as she thinks it would be nice if everyone had their own tree and people could even swap ornaments. Seki begins decorating the tree with a lot of Santa ornaments before sprinkling so much fake snow that it looks like the Santas were caught in an avalanche. Next he switches the tree on, which gets its power from the school's main via an extension cord, so the tree now looks like a scene from a horror movie and ruins Rumi's mood. The teacher asks for a volunteer to read something from the textbook and Rumi enthusiastically volunteers because by moving her chair back, the extension cord is pulled and the trees falls over and the Santas are freed. Seki is majorly annoyed with Rumi, who avoids making eye contact with him for the rest of the day.

As Mr Tani, their English teacher, is away on business (no further elaboration) Rumi and Seki's class have a self-study period and need to complete 2 worksheets, except Seki is taking this opportunity to sleep. Under Seki's pillow (because of course he would have one) is a picture of Seven Gods' treasure ship and if this ship appears in your first dream of the year then you will have good luck for the year and a good way to help you guarantee this is to have a picture of it underneath your pillow. Only problem is that is past new years, but Seki is having a pleasant dream so Rumi tests to see if that be changed by placing something else underneath - a worksheet perhaps. Seki's dream turns into a nightmare, Rumi decides to inflict more mental pain drawing a scary monster however, Seki doesn't find it scary and actually finds it amusing, so Rumi pulls her additions away from under Seki's pillow, moving it and waking him up in the process. Later, Seki shows off the monster he saw in his dream and it becomes a hit with the class.

Today is the school's annual kite flying day (seriously) and everyone has made kites in class and are flying at the riverbank somewhere within the town. However, not everyone is flying their kites as they have given up, such as Seki, although Dad-bot and Mum-bot are flying their kite and Rumi goes to sit next to them. However when she does, she unsettles them and causes them to break free from each other and Dad-bot starts to get pulled along by the kite, so Rumi chases after him but can't catch him before he hits the river. Dad-bot water-skis across the river and is slower than Rumi, who runs across a nearby bridge to the other side and retrieves Dad-bot and his kite, which contains Kid-bot. Seeing how reckless Seki has been with the robot family, Rumi takes upon herself to take good care of them and takes them home with her and doesn't tell Seki about it.

Rumi is now regretting taking the robot family home with her and she plans to return them back to Seki, but can't do it at school as it would be obvious that she took them and everyone would brand her thief (which she technically is). She instead decides to drop them off somewhere Seki would find them - such as the park where she met both him and his sister (and no, she can't put them in his shoe locker as that would incite the same rumours from the end of 7th Period). At the park, she begins to 2nd guess her idea as there is no guarantee that Seki will pick them up, but luckily she runs into Seki's sister (or more accurately Seki's sister runs into her) and she spots the robot family, but Rumi is able to convince her that A: she didn't steal them but instead she found them, and B: that she could return them to her brother without mentioning it to him that it was her. Seki's sister agrees to both points and tells Rumi her name, Jun. After reminiscing about her time with the robot family, Rumi gets ready to go home, only for Jun to come back and drag her to her home.
Rumi finds herself in Seki's room, wishing to be somewhere else, when Jun enters with a toy car and brings playing with it and Dad-bot (toy car goes zoom, Dad-bot hangs on for dear life). Rumi suggests playing something more girly and less likely to break a prized possession of a sibling, so they have a tea party and play until Jun is tired out, but before Rumi can leave, Seki enters his bedroom, so hse hides underneath his bed, thus making her situation worse. un wakes up and leaves Seki's room, knocking over some marbles (an activity for a later date) and some roll towards the bed, so Rumi decides to flick some of them away. However, one of the marbles hits Jun as she re-enters the room, causing her to trip and hurt herself, so Seki tends to her in her room, allowing Rumi to escape the Seki household. Rumi now fills her bag sweets in case she meets Jun again so she can apologise for leaving and not saying goodbye.

Seki is playing rugby (don't ask me which one, all we see is the scrum) with finger puppets with one one team being well financed, being able to afford cheerleaders and armour (which means they're playing American Football, not Rugby Football). The other team must make do with their coach as a cheer squad and normal albeit battered rugby equipment, although they ended up losing their coach after one of the cheerleaders lands on top of him and he gts arrested. Rumi is ready ot intervene for the underdogs, but they refuse, so she holds back but the teacher approaches their desks and in an effort to hide the puppet in his desk drawer, Seki accidentally jams his fingers and never resumes his finger puppet rugby game.

Rumi and Seki have got back their results from an English test and Rumi has passed with 82, while Seki didn't as he only scored 23. Seki isn't the only one with bad test scores as the class average was too low for the teacher's liking, so there will be a re-test on Friday and those who failed also have detention.
Friday comes around and Rumi is feeling confident, while Seki is using chance to decide his answers for the multiple choice questions as he has put numbers on the bottom of his pencil and rolling it and whatever number it lands on is his answer. I don't know how good this technique would be, but certainly wouldn't be quiet so could disturb his neighbours and runs on the assumption that each question has the same possible answers. However, not every question is multiple choice so the questions that require vocabulary knowledge, he attaches a 26-sided disc to his pencil and rolls that instead. This method won't work for all questions, such as one which requires you to work out where Tadashi is when leaving the station, so he divines Tadashi's location by using his pencil as a divination instrument. The comprehension question is about George Washington's youth, so Seki hypnotises himself using a picture of George Washington in an effort to become him (just keep him away from the local park or there will be a sudden case of deforestation).
The new test is marked and Rumi improves a bit to score 88, while Seki's unconventional methods score him 95, much to the annoyance of Rumi that she wants the class take another test.

The first bonus chapter is about Rumi discovering that her chair isn't properly balanced (not all legs touch the floor) and subtly makes it known to Seki, whose own chair has height adjusters fitted to the bottom to prevent his chair from having the same problem.
The second chapter is about the boys trying to predict the winning Football World Cup team (based on the Japanese publication date, would have related to then upcoming 2014 World Cup, which was 1 year, 2 months and 6 days away) and the girls not understanding the joy of it, whilst simultaneously predicting which boy would predict correctly.
The final chapter is autobiographical and is about that time Takuma tried to accrue enough points to get free bowl from a convenience store by buying their bread products and trials and tribulations he went through to try and achieve this.
