Baki has a strong sense of love and respect for those close to him. He is known to be very protective of his girlfriend, Kozue Matsumoto. He can become aggressive if she is threatened, such as when Sikorsky kidnapped her, and Baki hunted him down immediately to defeat him. By the second series of the manga, he's shown to be highly attached to his girlfriend, who acted as a great source of strength for him through her constant love and emotional support. Later, however, it has changed somehow, and they probably started to see each other less. At a certain point in the manga, Mohammad Alai Jr tried to gain Kozue's affection, which led to complications in the relationship between her and Baki. Possibly that's what caused this change. As a result, Hanayama is very intelligent, capable of effectively leading the Yakuza despite his young age. He is also fiercely loyal to his mother, which is evident in the way he takes care of her.

After some urging from his dad, he has sex with Kozue to get stronger. After they're done, Yanagi shows up, demanding a rematch against him. During their fight Sikorsky shows up and the convicts team up to fight Baki. Baki eventually takes Kozue and flees. But while Hanayama may be physically imposing, he is not a brute. Hanayama loves and respects his mother very much. His father died when he was a boy, so she has been the sole source of guidance and support in his life.Striking Strength: Wall level | At least Small Building level | Town level | Town level, likely higher

Mohammad Ali Jr tests a battle-eager Yujiro Hanma. Even though he's been poisoned, Kaioh Retsu enters Baki Hanma into the Great Chinese Tournament in China. Kaoru Hanayama (花山 薫, Hanayama Kaoru) is a major recurring character from the anime and manga series, Baki the Grappler. He is the extremely large nineteen year old leader of the Yakuza, who is one of the strongest characters in the series. Despite leading a professional criminal organization and wielding superhuman strength, he is a humble person with a strict code of honor: that should he falter/lose in a fight, it automatically means death; a family vow which has been held up for multiple generations.

Chiharu's second match was against boxing champion Iron Michael. Throughout the match, Chiharu relies on various dirty and illegal tactics to give him an advantage, including using his recently broken cast as a weapon and tying the pair's legs together with a cloth. However, Iron Michael is able to regain control of the fight and lands numerous powerful punches that nearly crippled Chiharu. Ultimately the victory went to Chiharu after Michael's hands were broken by his opponent's skull, but due to his numerous injuries, Chiharu is replaced by Alexander Gallen. Submission – one of Baki's signature moves from first series; used against Koushou Shinogi for the first time. It’s no secret that Baki Hanma and Hanayama Kaoru have a complicated relationship. From the beginning it was immediately clear that Kaoru is a very different person from Baki– whereas Baki is brash and confrontational, Kaoru is quiet and introspective. They first met when they were both young fighters looking to make a name for themselves. They had a fierce battle, and Baki emerged victorious.

Kaioh Kaku is the embodiment of Chinese Kenpo. Yujiro Hanma is known as the "Strongest Creature on Earth". A battle unlike any other begins. Spec unleashes moves lethal enough to take out even the strongest of opponents in one strike, but Kaoru Hanayama counters with improbable moves of his own. Spec finally tastes defeat.Kaoru usually wears glasses when he is not fighting and is almost always in his white suit. He also wears a blue undershirt and purple (later white) tie. He had an infamous showdown with the convict Spec, who manages to place a handful of bullets into Hanayama's mouth and slam it shut, causing them to explode his cheeks which creates two large holes on Hanayama's face and exposing a part of his jaw muscles. Although Hanayama won the battle, he wears a facemask for most of the series. His appearance has almost not changed in the five-year gap. Intelligence: High (Capable of effectively leading the Yakuza despite his young age, and knows how to effectively use his strength in combat)
