Season 1
Sleeve Salon
Okuno Kokoro (Sora Tamaki) is a first year high school student from today. After being sent off by the leisurely mother Hana (Akiko Kikuchi) and father Jun (TAIGA), she headed to high school with excitement. When I get to my seat, I can't help but notice Asuka Torii (Ten Yamazaki) in the next seat. The sleeves of the cardigan are ridiculously long! When I was asked, "Isn't the sleeves stretched right away?" And looked around the classroom, there were certainly students with various sleeve lengths sitting. "High school is amazing!" The curious heart is to sneak after Asuka, who says "I'm going to cut after school." And I arrived at the "sleeve salon". There, the heart is greeted by charismatic Sodeshi Masato Karis (Yosuke Sugino) and steps into a glittering unknown world ...
Nama lip
One day, classmates suddenly started speaking in various dialects. "Everyone comes from various places," he muttered, but the secret was hidden in "Nama Lip," which is very popular among young people. A mysterious announcement pops into my enviable ears, saying, "I want to apply raw lipstick too ...". When I jumped out in a hurry, there was a stall of raw lipstick! Then, the owner of a flashy Nama lip shop, Todo KOO, came out. Knowing that if you apply raw lipstick to your lips, you will be able to speak various dialects, Kokoro buys a local "raw lipstick" and heads for a certain person ...
Belly Bell
"Guu!" The sound of my stomach echoes in the classroom. The criminal, Kokoro, became embarrassed and secretly went to the corridor. Then, Suzunosuke Suzuki, the director of the "belly bell" that suddenly appeared, scouted "I have never heard" La "that is more beautiful than you!". "Haraberubu? La?" Apparently, the scale of the belly sound is different depending on the person, and it is said that the club activity that plays harmony with such a tone is the belly bell club. "If you get angry, youth is about to begin!" The heart that attracted me was to join the experience club. Every day I work hard with the members on various special trainings for the guerrilla concert. With the addition of childhood friend Kotaro Segawa (Toshiku Onishi), the power-up belly bell club will celebrate the long-awaited concert day.
Navy Blue Forest
Today is the day of work experience that my heart was looking forward to. Under the guidance of a social teacher, Yatsushiro Kaijin (Taro Yabe), the destination I went to with everyone was "Konso Farm". Rejoicing classmates. "Can we make navy blue soup?" Apparently, navy blue soup is made from eggplant, and while receiving the teachings of Navy blue soybean farmer Tamako Ashimoto (YOU), the eggplants are harvested and hollowed out. Experience making soup. "It's the first time I've been so excited about socks!", The excited heart goes to harvest the dark blue socks that were completed with everyone the next day, but for some reason I can't find my own socks. The reason was hidden in an "encounter" that I encountered while making dark blue socks.
Air Donuts
One morning. As soon as I go to school, I feel something is wrong. Everywhere, schoolgirls are on a diet. That should be it, the medical examination was approaching next week. When lunch comes, they open a tiny lunch box and bring healthy side dishes to their mouths. Asuka and Suzu (Yuna) answer, "Because I have to put up with it until after school," when I'm worried that "Is that enough?" According to the two, they will make "air donuts", which are perfect for dieting, in the kitchen after school. I was delighted that the air donuts that I wouldn't get fat even if I ate them said, "There is such a good story!", But it was a forbidden donut that "be careful of overeating" ...
Math Muscle
Kokoro and Kotaro are not good at math and have to take a follow-up exam. Kunihiko Koda (TAKAHIRO), a mathematics teacher, responds to Kotaro, who says "I wonder if there is something I can do suddenly", saying, "There is no such thing. Unless it happens even with Miracle Masmatics." It seems to be an urban legend that has been handed down at this high school, and one student said that he "suddenly became able to do math." I couldn't help but be worried about Miracle Masmatics, but I couldn't concentrate on studying after school, so I went to the health room for some reason. There, he meets Keiko Uchiji (Mitsu Dan), a teacher in the infirmary who knows the secrets of Miracle Masmatics, and asks him to teach him about the "math muscle" that exists in the human body ...
Killing Time
"I'm the only one in my spare time?" One day after school, my heart was mourning alone. All my classmates are not busy with club activities and salon reservations. In addition, my best friend Asuka says "Hurry up a little" and leaves. On the way home, I hear a mysterious voice. It was from "Himamashita Park". The heart that was just free, went inside to be guided. Then, the park manager, Tokiji (Jin Katagiri), who suddenly appeared, points to something like a magic circle drawn on the ground and tells me that I can kill time here. And it is said that "killed time" can be used only once when it is important. The heart that I will try immediately thinks that I will use the time I killed for something ...
Woman's Language
A certain break time. Kotaro, who was playing as a barricade, hides behind the curtains of a deserted classroom and finally falls asleep ... After a few minutes, he wakes up with a loud noise and looks around the classroom secretly. There were only female students in the area, and there was a barricade at the doorway. "What is this !?" And Reiko Koji (Ai Tominaga), who stands on the podium, starts the "Women's Language" class. Words that I have never heard fly around, and things like symbols are written on the blackboard. Kotaro couldn't catch up with his understanding, but when he remembered the letter that the girl student wrote during the morning class, it developed into a big uproar while involving his teacher, Kengo Kunimoto (Jaru Jaru). To go……
