The four student council members—Kaoruko Rukuonji (president), Ashe R. Sakuragi (vice-president), Mihiro Miyase (secretary), and Toa Narumi (treasurer)—are introduced. The four girls are doing their work on a hot day in June and sweating profusely in the student council room. Unable to stand the heat, Ashe proposes that they take off their clothes, owing to no one seeing them and anyway, they are all girls. At this idea, Mihiro agrees heartily and Kaoruko follows their example shyly. Meanwhile, Toa was just about to sneak off to the library to escape the heat and the embarrassment of taking off her clothes. However, the others spring up on her and despite her protests, begins to remove her clothes. Screaming, Toa pushes past them and hits the air-conditioner switch, causing the temperature to shoot up to a boiling 40 degrees Celsius. Now hotter than ever, all the girls express their desire to leave the room, but Kaoruko brings up a good point that the students would probably call them perverts.

Mihiro's family runs a Western restaurant, and she wishes for her friends to give her some dish ideas. Toa proposes snacks like ice-cream and potato chips, which are immediately eliminated. Ashe prepares a humongous bowl of udon for Mihiro to try next, but Mihiro refuses. Lastly Kaoruko prepares a simple meal of bitter curry and rice, to which Mihiro happily wolfs down before screeching two seconds later that it is too spicy. Kaoruko, surprised, tries it, and adds more spices to it instead. In the end, Mihiro's family restaurant's new menu for the summer was still a great success.

Kaoruko, who illustrates manga, is unable to portray the character in the manner she wants it too. So she asks Mihiro and Toa to help by modelling for her. Toa initially refuses, but after espying the prize: Hokkaido Limited Edition Potatoes, Maya no Mezame (マヤのめざめ, literally Maya's Awakening), she 'turns' into Kaoruko's servant in order to get them. As the 2 girls model and Toa is asked to kiss Mihiro, Ashe saunts in to see the both of them kissing. Blushing furiously, Ashe hurriedly apologises and immediately try to leave the student council room in embarrassment, while an embarrassed Mihiro tries to explain the situation.

Due to Kaoruko's constant sketches of manga, the floor is now littered with balls of used paper. Toa and Ashe do not seem to mind as they feel that the cleaner is coming on the weekends to clean up anyway. Their lazy manner is changed to fear when Kaoruko notices a cockroach scuttling among the papers. Screaming, the three girls except for the fearless Mihiro huddle in a corner and they beg Mihiro to kill it. At once, Mihiro is prepared to take action, scrolling up a piece of paper in her hands, she slams it down on the cockroach, which is killed immediately. The girls are greatly relieved, but Mihiro, due to experience of running a restaurant, knows that there are bound to be more cockroaches, ordering them to clean up the student council room. After cleaning, the student council room has seemingly magically turned clean. However, there seem to be many more under the chest of drawers.

Ashe is spooked out after reading a book of horror stories she borrowed from Kouki. Due to the late hour, she heads for home, but is spooked out by the dimness and silence of the school. Suddenly, she is spies many crows flying about, and runs away down the hall in fright, and down the stairs. There, she is freaked out by a faceless girl wearing a dripping wet uniform and sprints back up to the student council room, where she meets Toa. However, as Toa stands up to greet her, Ashe realises that Toa's face resembles a deathly pale ghost face, and faints in fright. In truth, the crows were flying to Mihiro, who was feeding them bits of grain and rice. The faceless girl was actually Kaoruko, whose black locks happened to fall over her face. Her uniform was wet as the faucet had broken and sprayed her with water. Meanwhile, Toa was chewing some bubble gum, which when popped, splattered onto her face in a white gooey glob.

Kaoruko gets excited after noticing a strange paper that Toa's brother, Kouki, left on the desk in the student council room, believing it to be the key to writing the next chapter of their Manga. In the end, Kaoruko supposedly solves it after looking through ancient Sumerian writing, converting it via calculation of Saturn's orbital period, omitting all 'noise' texts, before translating it to Aomori text and then ancient Japanese text, revealing the message: In the seventh month of 2016, the human race will die. Kaoruko innocently believes the message, and begins to weep but Mihiro and Ashe find it rather ridiculous. As the 3 girls begin to argue, Toa arrives, take a glance at the note, and explains to them that her brother's handwriting gets very messy when he is in a hurry, helping them translate the message: I am in a supplementary class because I failed a test, so I'll be late. This proves to be something totally unrelated to what Kaoruko originally made it out to be.

Kaoruko has bags under her eyes due to how she has been burning the midnight oil. Ashe and Mihiro, noticing this, are determined to put Kaoruko to sleep and let her have some rest. Mihiro sings her a lullaby while Ashe tucks her in, but this does not appear to work. Ashe then tries hypnosis therapy but gets hypnotized herself instead. In the end, Toa proposes a CD of sleep-effective music which she just bought recently. This soon proves to be effective and Kaoruko is soon fast asleep. The other girls then prepare to do some work. When Kaoruko wakes up feeling refreshed, she espies the other girls had been fast asleep as well, thanks to the CD.

There is a robot in the Student Council Room that can supposedly help with school life. Ashe, excited at seeing a robot for the first time, is keen to examine it but accidentally breaks off the robot's head. Mihiro then lets Ashe be the 'new robot' instead by wrapping her with cardboard and stashing the real robot away. Kaoruko is also excited to meet the 'new robot' and has it do much work for her. However, Toa seems to suspect something. Mihiro is nervous that Toa will figure out that the robot is actually Ashe, but actually Toa had received a note from the Faculty Office earlier in which the company requested that they bring back the robot as there is a critical design error. A resigned Mihiro then knows that the jig is up, while an unsuspecting Ashe is still being used by the president to do chores.

Mihiro has found a cat outside the school and takes it to Toa, asking for help to find its owner as there is a collar around it. Toa agrees but Mihiro then asks Toa to take care of the cat too as she lives at a restaurant, and pets are not allowed. Toa sighs and agrees. She writes plenty of notices and request that the other girls help her out by distributing them at the school gate. So far, there had been no replies and the cat is instead wreaking havoc and causing a lot of inconvenience for Toa. In the end, the find the owner of the cat and both the owner and the cat thanks Toa gratefully, ending with the cat's grateful mews resounding through the cool evening air.

Since the academy's website can now upload videos, advised by the teachers, Kaoruko wants the Student Council to upload a movie. They throw some idea for the movie's theme; academy love story, horror, science fiction, ESP, gourmet, and serial drama. In the end, they make a movie by using all of the themes: In a dystopic Ohnari Academy, the Glutton Empress Arche is challenged by Mihiron in an eating contest. Empress Arche choked, so Mihiron wins the contest. Out of nowhere, a mysterious ESP user (portrayed by Kaoruko) revives Arche with her puppeteering skill. In return, out of Axis-kun the robot (who happens to also be the judge of the contest), a ninja appears (portrayed by Toa), defeating both of the enemies. Toa's deed has somehow managed to steal Mihiron's heart, as the preview ends in a hanging scene, asking the viewers to look forward for the full movie for the conclusion of the forbidden love. Kaoruko seems pleased about the movie, while Ashe and Mihiro object to the action of uploading the bad movie.

The girls are at a spa resort having fun at the pool, and Ashe shows them how to dive. She executes it perfectly, but loses her bikini top in the process. The plot thickens when Ashe's bikini top is left floating towards the 'Dangerous Zone' of the spa resort, which Mihiro foresees that there will be a lot of dangerous creatures there. However, they still venture into the 'Dangerous Zone', and get sidetracked by whirlpools, big waves and geysers. In the end, Ashe manages to get her bikini top, but slips down a long and slippery slide, thankfully emerging unhurt and with her bikini top. However, Ashe's bikini bottoms are floating away now.

Toa's brother, Kouki Narumi comes to the student council room, only to get himself asked to buy foods; oshiruko for Mihiro, miso soup for Ashe, oden for Toa and tom yam for Kaoruko. The instant he leaves, all of them breath a sigh of relief, and starts preparing for Kouki's surprise birthday party. They want to thank him for all he has done, while Toa pointing out that they rely on her brother too much, and lately he spends more time outside than in the student council. When Kouki returns, they greet him and wish him a happy birthday, with Kaoruko praises him for managing to find the tom yam she orders.
