yoruhashi’s Manga, Explained: The Kingdoms of Ruin, Rega in the Sleeping Forest and the New Series

yoruhashi is one of those manga authors whose name travels further than any single title. Most readers meet the work first, through the anime of The Kingdoms of Ruin, and only later work out that the same person wrote and drew three other series in the space of four years. This guide covers all of them: what each one is, how long it ran, what is available in English, and where to start if you have not read any of it.

Who yoruhashi is

yoruhashi writes and draws, with no separate artist credit on any of the series below. The earliest work in this group is The Kingdoms of Caliburn (Tsurugi no Ōkoku), and The Kingdoms of Ruin is written as a sequel to it. Beyond that, the public record is thin. There is no author interview culture around this creator the way there is around some of their contemporaries, and the manga themselves do most of the talking.

What connects the series is a mood. Someone loses a person they loved to an institution, and the story becomes about what that person does with the rage. It is not a cheerful body of work.

The Kingdoms of Ruin

This is the big one, and the one that got adapted. Serialization began in Mag Garden’s Monthly Comic Garden on April 5, 2019, and ran until June 9, 2026. Chapters also appeared on the Manga Doa, Mag Comi and pixiv Comic websites. Fifteen collected volumes came out between October 2019 and July 2026, with the last one closing the series.

The premise is a witch hunt with a personal face. In a world where humans and witches once worked together, the Redia Empire decides magic is obsolete and orders witches eradicated. Chloe, a witch, raised the human orphan Adonis and taught him her craft. When the empire catches and executes her, Adonis swears revenge on humanity. His rage makes him unpleasant company for a long stretch of the story, and the manga is honest about that. He eventually allies with another witch, Doroka, and the relationship between the two carries the back half.

Yokohama Animation Laboratory produced the TV anime, which aired from October to December 2023. Crunchyroll streamed it as it aired and later added an English dub. Seven Seas licensed the manga in April 2020 and has been releasing it in English since.

Fifteen volumes is a complete story with an ending, which matters if you are deciding whether to commit. If you bounce off the anime’s first few episodes because Adonis is hard to like, that is the intended effect, not a misfire. Whether the payoff justifies the slog is the argument people have about this one.

Rega in the Sleeping Forest

yoruhashi’s follow-up launched in Kodansha’s Bessatsu Shōnen Magazine in August 2025 and ended on March 9, 2026, at two collected volumes. The second volume shipped on April 9.

Two volumes and seven months is a short life for a serialization, and the final chapter reads like a midpoint rather than a conclusion, which is the shape cancellations usually leave behind. Treat it as a short, unfinished piece of work rather than a complete one, and you will enjoy it more.

The good news is the English release. Kodansha USA licensed the series and plans to start publishing it in spring 2027, which makes it the only yoruhashi manga outside The Kingdoms of Ruin with a confirmed English edition.

Kokusan Shōjo Clarith

The odd one out of the group. Kokusan Shōjo Clarith (Domestically Produced Girl Clarith) started in Kodansha’s Shōnen Magazine Edge in December 2022. When Edge ceased publication in October 2023, the series moved to Kodansha’s Comic Days app in January 2024, and it reached a second volume in December 2023.

It has no English release that I could confirm, and it is the hardest of the four to track down outside Japan. If you are working through the catalogue in order, this is the gap.

Tatarigatachi

The newest series, Tatarigatachi -Dochakushin Geigeki Gakuin-, starts in Akita Shoten’s Weekly Shōnen Champion on October 22, 2026, in issue 47. The magazine announced it in issue 46 on October 15.

Raran is a boy whose older sister prays constantly to the cat god in the mountain until a divine disaster kills her. He responds by vowing to destroy every curse in existence. The magazine’s promo line sells it as a sword-fighting revenge story, which tells you what kind of serial Champion thinks it is buying.

No English release or simulpub has been announced. For now it exists in the Japanese magazine only.

Where to read each one

The Kingdoms of Ruin is the easy one. Seven Seas publishes it in English, and the anime is on Crunchyroll with subtitles and a dub. The Japanese chapters were hosted on Mag Comi, Manga Doa and pixiv Comic, all of which are region-locked to varying degrees.

Rega in the Sleeping Forest has no English edition yet. Kodansha USA’s release begins in spring 2027, so anyone reading in English is waiting. The Japanese volumes exist now.

Kokusan Shōjo Clarith ran in Shōnen Magazine Edge and then on Comic Days, and English availability is unclear.

Tatarigatachi begins October 22 in Weekly Shōnen Champion, in print and through Akita Shoten’s digital channels.

Reading order

Chronologically is the cleanest way through: The Kingdoms of Caliburn, then The Kingdoms of Ruin, then Kokusan Shōjo Clarith, then Rega in the Sleeping Forest, then Tatarigatachi when it starts.

If you only want one, start with The Kingdoms of Ruin. It is finished, it is the longest, and it is the only one with both an English edition available now and an anime to sample first. Watch two episodes on Crunchyroll, and if the tone works for you, the 15 volumes are waiting.

If you want to watch a creator develop, go the other way and read the newer work as it lands. Rega is short enough to read in an afternoon once Kodansha USA puts it out, and it shows what yoruhashi does with a smaller canvas and less time. Tatarigatachi is the one to watch over the next few months, because a weekly schedule is a different test than anything in the catalogue so far.

What to expect from the new series

Every yoruhashi series so far opens with a death and a promise of violence, and there is no reason to think the new one breaks the pattern. The difference this time is the magazine. Weekly Shōnen Champion publishes at a pace that forces shorter chapters and faster escalation, and it has a readership that expects a hook in the first twenty pages.

Whether that suits this author is the open question. The Kingdoms of Ruin took its time building a world before the revenge machinery took over, and a weekly slot does not always allow that. If the first arc of Tatarigatachi feels rushed, that will be why.
