Reference excerpt

Someone Hertz (Japanese: さむわんへるつ, Hepburn: Samuwan Herutsu) is a Japanese manga series written and illustrated by Ei Yamano. It has been serialized in Shueisha's shōnen manga magazine Weekly Shōnen Jump since September 2025. As of August 2026, four volumes have been released. The manga follows the extracurricular activities of two contemporary high school students who are dedicated fans of a late night comedy radio show.

Plot Mimei and Kurage listen regularly to the weekly late-night radio show Monday Midnight Talking (Mon-Mid), which features the hosts The Long Hopes, a manzai duo consisting of Osera and Koyama, reading jokes submitted by listeners on air. Mimei, who succeeds at nearly everything he tries, has never had a joke read on air, and idolizes an amateur comic who uses the pen name "Eel Potato" and has a submission read nearly every week. After his friend Kurage confesses to being "Eel Potato", she adds that she will not date anyone who is less funny than her. Is his renewed motivation (and her encouragement) to have his submissions read on-air born out of his frustration, her sense of competition, or from genuine romantic interest?

Characters

Main characters Mimei Fukumori (梟森未明) / "Owl in the Woods" (「森にふくろう」, Mori ni Fukurō) Voiced by: Kazuki Ura (PV and voiced comic) A serious, studious second-year student who is at the top of the class academically and athletically, but has a significant deficit of his secret passion, comedy. Since discovering Mon-Mid while studying for high school entrance exams, he has submitted jokes diligently for three years under the pen name "Owl in the Woods", but none of them have been read on the air. Kurage Mizuo (水尾海月) / "Eel Potato" (「うなぎポテト」, Unagi Poteto) Voiced by: Saku Mizuno (PV and voiced comic) Kurage is quick with a pun when speaking with other students and despite assumptions, does not have a boyfriend, vowing that she will not go out with anyone who is less funny than her pen name, "Eel Potato", who has won a minor following through her submissions to Mon-Mid.

Other listeners Natsu Akabane (赤羽ナツ) / "Bat Bahtz-Waru" (「バットばつ悪」, Batto Batsu Aku) A 22-year-old entrepreneur who runs a cafe; Natsu expresses some jealousy over Mimei's relationship with Mizuo. She met Mizuo at the previous Listener Koshien, a competition between the top ten submitters, determined by the number of entries read on-air; she uses the pen name "Bat Bahtz-Waru". Shuri Ebina (海老奈シュリ) / "Shrimp Sushi" (「えびのおすし」, Ebi no o Sushi) An 18-year-old fan of Mon-Mid who fell just behind Eel Potato in the prior listener Koshien. She is socially awkward, having no one in real life with which to share her love of comedy. Torano Karino (狩野虎乃) / "Iron Man of Cold Chinese Noodles" (「冷やし中華の鉄人」, Hiyashichūka no Tetsujin) A 27-year-old advertising agency employee Shintaro Shirokuma (城熊晋太郎) / "Don't Pass Middle Infield" (「抜けないで二遊間」, Nukenai de Niyūkan), later "Don't Leave the Team, Middle Reliever" A 19-year-old part-timer and serious baseball fan; he later changes his on-air name, prompting the Long Hopes to ask what is happening to his team. (?) / "Eight Guys in a Four-and-a-Half-Mat Room" (「四畳半に8人」, Yojōhan ni 8-ri) His identity and age are unknown, as he showed up to a public meeting wearing a paper bag over his head Ryuji Kamakiri (鎌桐竜司) / "Chupet of Love" (「恋のチューペット」, Koi no Chūpetto) A 23-year-old researcher. Chupet is a soft drink which was packaged in a tubular polyethylene container, popularly frozen and sold as a freezie until it was discontinued in 2009 due to manufacturing issues. Ryusuke Nekota (猫田良介) / "Super Town Mayor" (「超町長」, Chō Chōchō) A 42-year-old employee of the town hall Hideto Miyamoto (宮本英人) / "Hateful Eight" (「ヘイトフルエイト」, Heitofurueito) A professional comedian who belongs to the same agency as the Long Hopes Mokomo Watanuki / "Do Gummies Count as Snacks" A cheerful girl who is a fan of the Long Hopes and regularly submits entries. Reiji Takayama / "Noise-Canceling Junkie" The childhood friend of Mokomo who has been submitting entries to Mon-Mid solely for his resume, as he wants to work in media. He is rather direct.

Publication Written and illustrated by Ei Yamano, the series began serialization in Shueisha's shōnen manga magazine Weekly Shōnen Jump on September 16, 2025. As of August 4, 2026, the series' individual chapters have been collected into four tankōbon volumes. Viz Media and Manga Plus are publishing the series in English simultaneously with its Japanese release. A collaboration with the late-night radio show All Night Nippon was held to commemorate the release of the first volume.

Reception Kittun Nozomi of Real Sound felt that the comedy was more relaxed than Akane-banashi and Beshari-Gurashi, two other comedy manga published in Weekly Shōnen Jump. They also liked the focus on the late-night radio subculture and the story's setting. Radio personality Hikaru Ijūin discussed the manga during an episode of his show. The pre-orders for the first volume sold out on Amazon Japan. By May 2026, the series had 300,000 copies in circulation. By August 2026, the series had 500,000 copies in circulation between its print and digital editions. The series has been nominated for the twelfth Next Manga Award in 2026 in the print category.

Worked examples

Example 1 — a first encounter with Someone Hertz

Start with the simplest possible case. Write down what Someone Hertz claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Someone Hertz before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Someone Hertz ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Someone Hertz

In research: Someone Hertz appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Someone Hertz in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Someone Hertz is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2025 manga, Fiction about radio, Manga series, so understanding it makes those chapters shorter.
In everyday life: Look for Someone Hertz outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
