Shueisha added Hiromasa Okujima’s comedy manga Together with Serial-san to its free online platform Manga Million on October 14, 2026. The series began in Shueisha’s print magazine Grand Jump Mucha on February 25. It tracks college student Chihiro Yoshida after he makes an unusual living pact with a fugitive killer. It’s a dark comedy about a dangerous identity swap that the publisher now shares with web readers all over the world without fee barriers [1].
Chihiro Yoshida Meets a Fugitive in Serial-san
Chihiro Yoshida lives an easygoing life defined by total personal freedom and regular debauchery until a high-profile serial murder case grips the public. The killer arrives at his front door without warning. Yoshida quickly realizes that panic won’t save him from immediate danger. He chooses a strange way out of the crisis and makes a surprising offer: “Why don’t you assume my identity and live here?” [1].
That unexpected proposal starts an impersonation cohabitation where getting caught isn’t an option for either man as they try to share a single home under one name [1]. Okujima leans on his talent for drawing handsome men to build sharp humor between two completely different roommates who must hide from the police while learning each other’s habits [3]. The tension grows out of daily deceit. Yoshida spends his days trying to keep up regular routines while harboring a fugitive guest in plain sight. It’s a story that blends criminal suspense with absurd domestic situations as an unruly student manages to turn mortal peril into a strange kind of chaotic fun [1].
Readers can dive into the opening chapters without paying any subscription fees or filling out long profile forms on the site. The web release lets global readers follow the high-stakes game through an ordinary web browser on desktop or mobile screens [4]. Yoshida’s gamble keeps the jokes moving fast because any small slip could bring the police straight to his apartment door [1].
Hiromasa Okujima Expands His Catalog on Manga Million
Hiromasa Okujima built a broad creative catalog with several Japanese publishers before bringing Together with Serial-san to Manga Million. His vampire comedy Baban Baban Ban Vampire began in Akita Shoten’s Bessatsu Shonen Champion magazine in October 2021 and grew into a major favorite. Volume 14 arrived on August 6. Netflix released an animated version of the vampire tale in January 2025. A theatrical live-action movie debuted five months later in July 2025 [2].
Okujima also worked with author SHOOWA on Bad Boys, Happy Home, which ran in Japan under the title Dōsei Yankee Akamatsu Seven. That boys-love series started in Akita Shoten’s Kachi Comi magazine in April 2018, and Viz Media picked up the work for English audiences through its SuBLime imprint. SuBLime published the first volume in both print and digital formats in July 2021. The release found eager readers overseas who appreciated his detailed character art [3].
These varied projects show how easily the artist handles different demographics, shifting from delinquent romance to bloody comedy without losing his expressive visual touch. His characters stand out because he gives them sharp facial details and expressive eyes that make absurd situations feel lively on the page [3]. That versatility explains why Shueisha chose to add his work to its global showcase [2].
Grand Jump Mucha Roots and Live-Action Adaptations
Before landing on the web service, Together with Serial-san started inside Shueisha’s seinen print magazine Grand Jump Mucha [1]. The January 2026 issue of the magazine first told readers that Okujima would launch a new story, tentatively called Serial-san, in the next issue on February 25. Shueisha gave the premiere strong backing with a color opening page and front-cover artwork on the issue [5].
Live-action adaptations are familiar territory for Okujima’s back catalog, as shown by his comedy manga Katei Kyōshi no Kishi Knight Desu., known in English as I Am the Home Tutor Kishi Knight. Okujima serialized that story in Akita Shoten’s Nicchan Gecchan magazine back in 2019. Akita Shoten published only one compiled volume. A live-action series adaptation of the work debuted on television on January 5 after producers noticed the comedic appeal of the premise [1].
Japanese magazine readers responded warmly to Okujima’s comedic timing in print. Shueisha’s decision to translate the title gives overseas fans a quick way to catch up with his ongoing work [1]. The Japanese preview in Grand Jump Mucha described the premise as a tale of cohabitation between a self-indulgent student and a serial killer, pointing out the funny contrast between Yoshida’s laziness and his guest’s violent reputation [5]. It’s a fresh angle that fits well with Shueisha’s broader efforts to digitize new seinen titles for readers outside Japan [1].
How Shueisha Manga Million Operates as a Centenary Project
Shueisha launched Manga Million on August 6, 2026 as a major gift to celebrate the company’s 100th anniversary. The special digital reading project stays open until December 31, 2027. It allows fans around the globe to read roughly 400 manga series and one million pages without paying for individual chapter unlocks. Unlike platforms where eight new manga series expand the Manga UP! global catalog behind token gates, Manga Million runs fully inside web browsers without asking users to download standalone apps or buy coins [4].
The website holds formal copyright clearance with ABJ Mark registration number 10921077, verifying that every single chapter comes straight from the official rights holder [6]. Visitors can start reading legendary hits like Eiichiro Oda’s One Piece, Masashi Kishimoto’s Naruto, and Tite Kubo’s Bleach without any signup steps. Other popular classics on the virtual shelf include Tsugumi Ohba and Takeshi Obata’s Death Note, Yoshihiro Togashi’s Hunter x Hunter, and Hideaki Sorachi’s Gin Tama, as well as darker series like Hiroya Oku’s Gantz and Sui Ishida’s Tokyo Ghoul [4].
Around 30 ongoing manga series also get their latest chapters added to the service on a brief delay after their Japanese release dates. That setup gives readers a steady reason to check back each week, turning the anniversary site into an active reading hub rather than a static archive. It’s a generous model that lets manga fans explore unfamiliar works without risking money on blind purchases [4].
Global Catalog Access Across Languages and Web Browsers
While promotional materials mention translations across more than 100 languages, practical language choices vary widely depending on which title a reader selects. A detailed catalog review by Jam Hsiao on Sumi shows that 382 titles are live on the service today, with about three out of four series available only in English. One Piece stands as the true multilingual leader with chapters in 107 languages, offering an opening run of 108 chapters, while French offers 84 series, Spanish lists 81, German has 70, and Brazilian Portuguese counts 62 [4].
Readers who keep up with industry trends through exclusive digital manga additions on the Emaqi platform can see how Shueisha balances classic backlogs with current serialization hits. The platform carries recent favorites like Demon Slayer, Jujutsu Kaisen, My Hero Academia, One-Punch Man, Haikyu!!, and Chainsaw Man. It also features current breakout series including Dandadan, Kagurabachi, Sakamoto Days, and Kaiju No. 8. Newer manga enthusiasts can sample each of these popular series free of charge [4].
Adding Together with Serial-san proves that Shueisha wants to show varied seinen humor alongside its famous shonen battle blockbusters. The browser platform doesn’t ask for credit cards or user accounts, so curious manga fans can start reading Yoshida’s misadventures right away. With the anniversary showcase scheduled to close on December 31, 2027, global audiences have plenty of time to enjoy Okujima’s funny tale of killer roommates before the celebration ends [4].
