Demon Face (鬼の形相, Oni no Men) is a special fighting skill of the Hanma family.


The Demon Face is a "technique" in which the user very forcefully flexes the back muscles to form the face of a demon. The user becomes many times stronger to their level prior to activation in every aspect, experiencing an increase in physical strength, speed, endurance, stamina, etc. The user can virtually absorb any hit, such as when Yuujiro Hanma ceased taking damage from Kaku Kaiou's Offensive Shaorii strikes, which normally produce enough force to shatter walls. Additionally, the user can dish out massive amounts of damage in return.

In truth, the Demon Face is not so much a technique as it is a predetermined advantage such as height or muscle-building capacity, since it is a gift depending on genetics and bloodline. However, it can be treated as a technique since it is only activated when the user decides to use it.

Known Users[]

The Demon Face is a gift bestowed on the Hanma bloodline. It has three known possessors.

  • Yuujiro Hanma. Yuujiro uses his Demon Face on many occasions, as he is well aware that he is superior to all other fighters and does not see it as an unfair advantage, believing that anything you have at your disposal is fair in a fight - be it a gun, sword, or (in his case) genetic gift. As he is the image of evil or wickedness in the series, Yuujiro sees no problem with using it.
  • Baki Hanma. Baki, being the son of Yuujiro, also possesses the gift of the Demon Face. However, due to his nature directly contradicting Yuujiro's and him being a kinder and more honorable fighter, he abstains from ever using it. He's only known to have used in two instances, when he first developed it in his fight with his half-brother Jack Hanma during the Maximum Tournament Saga to level the playing field and later on in his final battle with Yuujiro, which was a no-holds-barred fight and simply consisted of the two of them trading blows with one another. He was also briefly seen having it during his fight with Oliva, but it was unknown whether or not he actually put it into use in the actually conflict or just to quickly recover his energy from the beating he'd been receiving at that point.
  • Yuuichiro Hanma. Yuuichiro is seemingly the first possessor of the Demon Face, since he is the father of Yuujiro and the earliest link known to have it, since we do not know of Yuuichiro's (nor the rest of the Hanma clan's) ancestry. Yuuichiro is never known to use the Demon Back, and because his personality and character is similar to Baki it is fair to assume that he never used it or did so only in extreme occasions. However, in Baki's final fight with Yuujiro when the manga illustrates Yuuichiro's past and fight against the US Navy, he is distinctly shown and described having the Demon Face.

One member of the Hanma bloodline that is excluded for an unknown reason is Jack Hanma. Jack is Baki's half-brother, and has a different mother. He has never been known to have or have used the Demon Face, though it's ambiguous as to whether this is a result of him being born with a weak and frail body, constantly taking drugs that artificially enhanced his body, or just not inheriting the proper genetics to do so.
