Volume 20 Announcement and Cover

Volume 20 Arrives September 9

Yonezo has reconfirmed that the manga reaches Volume 20 on September 9, 2026, roughly three months after Volume 19 launched on June 9.

Kodansha has set the regular Japanese price at ¥759 including tax. The physical B6 edition contains 128 pages and carries ISBN 978-4-06-544767-3.

The release brings the adaptation to twenty collected volumes after the first book arrived in March 2022.

Orun Heads Into the Regrief Territory

According to Kodansha's official synopsis, Lazarus, sponsor of the Night Sky Silver Rabbits, gives Orun and his companions their latest assignment.

The party travels to the Regrief territory to investigate a labyrinth, presenting Sophia and the other members with an unfamiliar experience.

That shifts the manga into a new investigation away from the group's more familiar surroundings.

Hart's Ki Training Moves Into Practice

Orun previously learned about ki from Hart.

Volume 20 moves that development beyond training. Orun heads off alone with the intention of testing the technique under real conditions.

Kodansha has not disclosed what he discovers during that investigation or how successfully he can apply what Hart taught him.

The Manga Is Now a Major Part of the Franchise

Yonezo's adaptation began through Suiyōbi no Sirius in 2021 and has now reached its twentieth collected volume.

An official English version is also distributed through K MANGA under the title Jack-of-All-Trades, Party of None.

Meanwhile, Itsuki Togami's original light novel series, illustrated by Yuri Kisaragi, has reached ten volumes.

The Franchise Has Passed 6.4 Million Copies

The manga's continued growth comes alongside a wider expansion of the franchise.

Bandai Namco Filmworks confirmed in July 2026 that the overall series had surpassed 6.4 million copies in circulation. That figure represents the publishing franchise as a whole rather than sales of Manga Volume 20 alone.

The first anime season concluded after 12 episodes in March, immediately followed by confirmation that Season 2 is in production.

Season 2 Still Has No Release Window

Production of the second anime season is official, but no broadcast season or date has been announced.

Its announcement visual and trailer introduced a mysterious girl as one of the first hints toward the next stage of the story.

Until further anime details arrive, the manga and original novels remain the primary way to continue following Orun's journey.

Why This Matters

1) The manga has reached the Volume 20 milestone

Four years after its first collected edition, Yonezo's adaptation has entered double-digit territory twice over and remains ongoing.

2) Orun is putting a new ability into practice

The volume introduces not only a new investigation but also practical use of the ki technique he learned from Hart.

3) It arrives while the franchise continues expanding

Volume 20 follows the 6.4-million-copy milestone and confirmation that a second anime season is already in production.
