Is Baki Rahen Worth Reading? Review & Where to Read

Quick Answer
If you already know the Baki franchise, yes — this is Jack Hanma's book, and it leans fully into the body-horror, strength-obsessed id that makes the series what it is. If you're coming in cold, it's a rough entry point; this spin-off assumes you already care about Jack.
Quick Verdict
“Pure, undiluted Hanma-brother physicality — less a new story than a magnifying glass pointed at Jack.”
Best for: Existing Baki readers who always found Jack Hanma more interesting than his famous brother and wanted a book that agrees with them.
Not for: Readers who haven't read the mainline Baki series — this spin-off leans on history and character dynamics it doesn't stop to re-explain.

Overview
Baki Hanma has always had the title, but his brother Jack has always had the rage — a pure, uncomplicated hunger to get stronger that never needed a tournament bracket to justify itself. Baki Rahen hands Jack his own book, and true to form, it doesn't give him a new personality so much as more room to be exactly who he already was: a man who treats his own body as a problem to keep solving through force.
What it does well
Keisuke Itagaki's entire career has been built on one idea pushed to its most extreme, physically grotesque conclusion — what does it actually cost a human body to get this strong — and Jack has always been the character best suited to carrying that idea without a plot getting in the way. Freed from sharing panel time with Baki's wider rogues' gallery, Rahen can sit with Jack's specific brand of obsession for as long as it wants, and it does, following his trajectory with a singular focus the mainline series rarely affords any one fighter.
The body horror that's always run through Itagaki's art is, if anything, more pronounced here, which fits: Jack's whole character is the horror of what relentless self-improvement does to a body that was never meant to take this kind of punishment. The anatomy is still absurd, still committed to its own internal logic, still rendered with the same unflinching detail the franchise is known for. If you came to Baki for the sheer physical spectacle of men destroying themselves to get stronger, Rahen delivers that in a more concentrated dose than the ensemble mainline series usually allows.
Where it falls short
The concentration cuts both ways. Rahen isn't interested in re-explaining who Jack is or why his rivalry with Baki matters — it assumes you're already invested, and readers coming in without that history will find a lot of the emotional weight simply isn't there for them. The narrower cast also means less variety; without Baki's wider ensemble of fighting styles and personalities to bounce off of, a handful of chapters lean almost entirely on shock value and physical extremity rather than forward plot movement, which can wear thin in long stretches.
Verdict
For Baki fans who always wanted more of Jack and less of the tournament structure around him, Baki Rahen delivers exactly that — concentrated, uncompromising, and entirely uninterested in being anyone's first stop in the franchise.
Strengths & Weaknesses
Strengths
- Jack Hanma has always been the Baki franchise's most purely physical character, and giving him his own book lets Itagaki follow that obsession with strength to places the main series, split between an ensemble, never had room for.
- The body-horror streak that runs through all of Itagaki's work is dialed up rather than softened here, which suits a character whose entire identity is built around pushing his body past reasonable limits.
- Because the focus narrows to one man's trajectory instead of a tournament's worth of fighters, the pacing can sit with Jack's psychology in a way the mainline series rarely slows down for.
- It's recognizably the same artist doing what he does best — anatomy pushed to grotesque extremes in service of a very simple, very committed idea about what strength costs a body.
Weaknesses
- This is not a jumping-on point. Jack's dynamic with Baki and the rest of the cast is the emotional backbone of the franchise, and Rahen assumes you already have that context rather than building it from scratch.
- Without the mainline cast's variety of fighting styles and personalities, a few stretches lean entirely on shock value and physical extremity to carry chapters that might have used a bit more plot movement.

Do I need to read the original Baki the Grappler first?
Yes, strongly recommended. Rahen is built around Jack's established rivalry with Baki and his place in the franchise's cast, and doesn't re-introduce that context for new readers.
Is Jack Hanma the main character here?
Yes — Rahen shifts the focus from Baki to his brother Jack, following his own path and his constant drive to get stronger.
Where can I read it?
