It follows high school students Azemichi Shijima and Taiyo Higashikata as they aim to become the best comedy duo in Japan. Show-ha Shoten! was serialized monthly in Shueisha's Jump Square magazine from October 2021 to August 2025, with the chapters collected into eleven tankōbon volumes as of September 2025.

Shy high school student Azemichi Shijima and former child actor Taiyo Higashikata both love comedy. After learning that Azemichi is a skilled joke writer famed for regular contributions to a radio show under the pen name Everyday Shijimi, Taiyo tricks him into being his partner in a sketch comedy routine for their school's cultural festival. The sketch is a hit, with the two winning the award for best performance. Realizing that each excels in the area where the other is weak, Azemichi with writing comedy and when to transition and Taiyo with performing and ad-libbing, the two decide to team up and form the comedy duo One-Way Ticket to the Top. In order to earn the blessing of Azemichi's parents, they must win the bimonthly High School Comedy Battle. There, they meet and become rivals to the duo Sprechchor and come in second place behind Rising. However, Rising resigns so that One-Way Ticket to the Top are elevated to first place and can continue comedy. Azemichi and Taiyo then enter the Kanto-2 block preliminary round of Wara-1 Koshien, or "Wara-Ko" for short, a national manzai competition for high school students.

• Azemichi Shijima • A shy 16-year-old high school student who is obsessed with comedy ever since he failed to make his middle school crush, Mizuha, laugh at her request two years ago. She soon changed her last name and moved away. Not knowing her new name, Azemichi hopes he might be able to see her again if he becomes famous. He has already achieved some success by submitting jokes to TV and radio shows under the name "Everyday Shijimi", but that was anonymously because he has stage fright. • Taiyo Higashikata • Azemichi's schoolmate and a former famous child actor in historical dramas. Although a natural, he only acted to make his mother smile, and switched to comedy after seeing someone make her laugh at a joke. He was in a previous comedy duo, but his partner Sakutaro Kunugi died from a disease. Carrying on his former partner's dream, he wants to become the first person to win both the Wara-1 Grand Prix, a competition for manzai duos, and the Ultimate Comedy Battle, a sketch comedy competition. • Akane Hanamori • Azemichi and Taiyo's senpai who has been a big fan of comedy since she was a child. She is One-Way Ticket to the Top's biggest fan and trains them in manzai, while becoming something of a manager to them.

2022 Wara-1 Koshien finalists [spoilers] • Block — Team — Routine — Order — Place (pts) • Hokkaido / Tohoku — Passionate Sandbag — "Mid-level Delinquent" — 10 — 8 (530) • Kanto-1 — Rising — "Zombies" — 7 — 2 (572) • Kanto-2 — One-Way Ticket to the Top — "Our Story" — 9 — 1 (580) • Chubu — Brutus — "Rich Kid" — 4 — 6 (564) • Kansai-1 — Shiba Inu World Tour — "Reunion" — 8 — 4T (566) • Kansai-2 — Kamikaze Yellowtail — "Pro Swimming" — 2 — 9 (523) • Chugoku / Shikoku — Iwashi Tsuyoshi — "Spherical World" — 3 — 7 (531) • Kyushu / Okinawa — Broken Glass Slipper — "School Crossing Duty" — 1 — 4T (566) • Wild Card — Sprechchor (Kanto-2) — "Babysitters" — 6 — 3 (569) • Wild Card — Mega Beef Bowl XL (Chugoku / Shikoku) — "Dating" — 5 — 10 (499) • Shupurehikōru • A high school comedy duo whose name is derived from "a chorus of voices". It is composed of Teppeita "Tetta" Onizaki, a scary-looking man who is actually sensitive and caring, and Jun Mizushina, a self-confessed "prick". Although Tetta is a talented baseball player, he was bullied regularly as a first-year, and Jun found a way to let him quit the team and partner with him. As three-time finalists of Wara-1 Koshien, and with the most appearances at the High School Comedy Battle, they are the "most visible" high school manzai duo. They form a friendly rivalry with One-Way Ticket to the Top after meeting at the High School Comedy Battle. Having placed second in the Kanto-2 regional, they are selected as one of two wild card teams to participate in the 2022 Wara-1 Koshien. • Rising • A cocky, new comedy duo who beat One-Way Ticket to the Top at the High School Comedy Battle, their first competition; they are Atsushi Ban and Bunta Harigane. However, they resign so that One-Way Ticket to the Top win and Azemichi's parents can not force them to give up comedy. As the winner of the Kanto-1 regional, they are competing in the Wara-1 Koshien tournament. • Burūtasu • Brutus includes Tsutomu Nitta and Ryuki Nazutani, who is often seen eating, causing him to be overweight. As the winner of the Chubu regional, they are part of the Wara-1 Koshien tournament. Nazutani previously was in the duo Serinunteiusu with Sakutaro Kunugi, but Kunugi left to team up with Taiyo, so Nazutani holds a grudge against Taiyo for "stealing" his partner. • Kirameki Confections • A comedy duo composed of Daiboku Tabata, a very muscular man, and Suzume Kanade, a small female karateka. Their comedy is atypical in manzai in that it revolves around physical slapstick where Kanade strikes Tabata. • Garasunokutsu ga Wareta • Winners of the Kyushi / Okinawa regional. Unlike the other contestants, glasses-wearing Rinka Iwashimizu and silly Himawari Saeda have competed in the actual Wara-1 Grand Prix, reaching the third round; they are known as the top female comedians, pro or amateur. They met in high school, serving detention together as Himawari's provocation caused Rinka to lose her temper multiple times, disrupting their classes. Himawari's older brother and sister exceled in academics and athletics, so to stand out, she is the class clown; when their teacher Miss Miyuki yells at Himawari for not taking anything seriously and trying to ruin Rinka's life, Rinka defends her and vows to show the world how funny they can be together. • Kamikaze Yellowtail • Winners of the Kansai-2 regional. Daisuke Kazami and Kosaku Kamiyama are a "mismatched" pair, Kazami delivering lines smoothly and Kamiyama slowly and awkwardly. • Iwashi Tsuyoshi • Winners of the Chugoku / Shikoku regional. Yushin Mochizuki and Kanji Atago are two friends who hold a deep-seated grudge against Passionate Sandbag because they insulted and sabotaged Sweet Potato Combo at the prior year's Wara-ko finals. Oshino, their friend and coworker, was part of Sweet Potato Combo and joined the priesthood after graduation. • Tokumori Gyūdon Ōmori • Selected as one of two wild cards; competed in the Chugoku / Shikoku regional. Unlike the other groups, there are three members: Ichinosuke Koda, Takumi Nomo, and Takuya Tone. • Shiba Inu Sekai Isshū • Winners of the Kansai-1 regional in an upset over Pascal 800, which placed 4th at the prior year's Wara-1 Koshien. Shunsei Mimomi and Yo Onozuka are mismatched partners: while Shunsei smoothly delivers his lines, Yo speaks in awkward, explosive phrases, giving them a unique rhythm. • Passionate Sandbag • Winners of the Hokkaido / Tohoku regional; they placed second in Wara-Ko their first year, and won in their second year. Matsuri Okanda and Haruka Ataru have a mean-spirited comedy style, ridiculing their competitors with bullying observations, and as a result, are not well liked by other comedy teams.
