The manga adaptation of Ore ga Sodateta Saikyo Chara ni Tensei Shita node, Hamukau Yatsu wa Subete Bunnagutte Ikiru Koto ni Shimashita has received its first collected volume. Suiseisha officially released the tankobon in Japan on September 18, 2026, roughly five months after the manga began serialization through ComicFesta.
The adaptation brings Crosis' web novel into manga form with Kohei Kaku handling the artwork. It follows Kaisar, a duke's son repeatedly looked down upon for supposedly lacking magical talent until memories of his previous life reveal that his current body is the same VRMMO character he once personally developed to an overwhelming level.

Volume 1 Cover
From Digital Serialization to the First Tankobon
The manga moved into collected-book form relatively quickly. WWWave announced the adaptation on April 3, 2026, launching its initial distribution through ComicFesta.
On that platform, the story is sold as shorter numbered digital installments. At the time of verification, ComicFesta lists nine installments, each priced at 150 points.
That creates an important distinction: the Volume 1 released on September 18 is the first tankobon / collected edition, and is not equivalent to ComicFesta's earlier short “Volume 1” installment.
Sony Reader and Apple Books explicitly warn that the collected Volume 1 contains material previously published across digital installments 1–6.
Readers who already purchased those six parts individually should therefore be aware that the collected digital edition contains overlapping content.
Kaisar Realizes He Is the Level 99 Character He Once Built
The story begins with Kaisar in an extremely disadvantaged position.
Despite being born into a duke's family, he is regarded as the lowest of the low because he appears to lack magical talent. He is constantly compared with his more gifted younger brother and treated dismissively even by his childhood friend and fiancée, Liliana.
Everything changes when an incident restores memories from his previous life.
Kaisar realizes that his world is the same VRMMO he once played extensively, and more importantly, that he has reincarnated into the character he personally created and developed.
That character was anything but ordinary. Kaisar had invested heavily in it, bringing the build to level 99 with extremely powerful skills and statistics.
Once the “status reflection” setting is activated, the strength that had seemingly been absent begins to manifest through his current body.
The story's power dynamic immediately reverses: the person everyone considered powerless is actually carrying an endgame-level build far beyond the world's normal standards.
Revenge Becomes the Core Once His Old Power Returns
Both the publisher material and ComicFesta position revenge as one of the manga's defining elements.
Kaisar does not decide to quietly hide his strength and pursue a peaceful second life. Remembering how his family and those around him treated him, he instead chooses to use his recovered abilities against the people who abused and humiliated him.
That intent is reflected directly in the series' unusually long title, which emphasizes his decision to punch down anyone who stands against him.
The game mechanics are not merely decorative, either. Status values, skills, saved character data and Kaisar's knowledge of his former game all explain why his apparently impossible power exists.
ComicFesta officially categorizes the series with fantasy, revenge, special abilities, isekai/reincarnation and dark tags, making its retaliatory tone part of the manga's formal positioning.
The Source Web Novel by Crosis Is Already Complete
Before the manga adaptation, the story existed as a web novel written by Crosis.
Its Kakuyomu edition is now marked complete at 233 chapters. The work page describes how the protagonist is initially belittled by his parents, younger brother and fiancée before discovering that he has reincarnated as the game avatar he once built himself.
Crosis also notes on Kakuyomu that the work previously used an even longer title before adopting the current name now used by the manga.
When the comic adaptation began in April, Crosis specifically identified Kohei Kaku as the artist handling the manga version.
September's tankobon therefore represents another stage in the progression from web novel, to serialized digital manga, to a physical collected book.
Volume 1 Has Several Retailer Bonuses
Suiseisha prepared several retailer-exclusive bonuses for the first collected volume.
Selected Kikuya Shoten stores offer an illustration card.
Gamers has a newly drawn bromide.
Sanyodo offers another illustration card.
Melonbooks has a newly drawn illustration card.
Selected supporting bookstores also provide a reproduction-signed paper as a common bonus.
Availability depends on individual retailers and remaining stock, meaning a single copy does not automatically include every listed bonus.
Physical and Digital Editions Differ Slightly
Suiseisha's physical edition is a B6 book with 160 pages according to its bibliographic record.
Its official price is ¥858 including tax, and the ISBN is 978-4-434-38027-3.
A collected digital edition launched on the same day through retailers including Sony Reader and Apple Books. Those listings both give the digital version a 166-page count, meaning its pagination differs from the physical bibliographic record.
Sony Reader lists the digital edition at ¥858, while Apple Books showed ¥850 at the time of verification. Digital pricing can vary by retailer.
Both listings consistently note that this collected edition reuses material from earlier digital installments 1–6, allowing existing readers to avoid accidental duplicate purchases.
Why This Matters
1) The adaptation reached tankobon form quickly
Serialization only began in April 2026, while the first collected volume was already available by September.
2) The distinction between installments and tankobon matters
ComicFesta already lists nine numbered digital parts, while the newly released collected Volume 1 compiles the first six.
3) The protagonist's game build is directly tied to his power
Kaisar does not simply receive random abilities after reincarnation; his overwhelming strength comes from the level 99 VRMMO character he personally created in his previous life.
4) The source novel already has a completed story
Manga readers are entering an adaptation of a web story that has already reached its ending across 233 chapters, while the comic itself remains comparatively early.
