Akira Yamato

Akira Genryusai Yamato also known as The Mighty Demon (, Gōma), is the former fighter of former Kengan Association chairman, Mitsuki Metsudo, being the original holder of the title of Fang of Metsudo (の, Metsudō no Kiba) and the former clan leader of the Kane Clan.

Appearance
Akira is an elderly man and walks with a slight hunch in his back. He has light blue eyes and tan skin. He has spike white hair, thick white eyebrows, and a thick white mustache. He wears a long-sleeved black martial arts jumpsuit, light-colored pants, and Tai Chi slippers. Despite his old age, his body is lean and very muscular, and it is covered in scars from his various battles in Kengan Matches from when he was young.

Personality
Akira is man that loves to fight he recalls when he took on 50 martial artists at once and was extremely reckless in his youth and violent to boot, to the point where he deliberately spilled tea over another relaxing fighter's head just to goad him into fighting. Akira would take on anyone, man, woman, child, and even animals. To this date, Akira still takes on anyone. Akira has stated that he has never been defeated he says he was just naturally strong and superior to all humans.

In his presentation, the aged state, Akira is a kind old man who has been wizened from his experiences. However, he still possesses a reckless streak and can also be very arrogant, the former of which is shown in his tendency to spend his family's money as well as getting carried away whenever he gets a chance to showcase his strength.

He also tends to speak out his often over-simplified plans to others through even much more over-simplified and blunt manners of speech (e.g. "The fight until you're the last one standing plan", "The run and run and until they finally catch you plan" and "The giant dealing with it when it comes plan"). He's rather cocky in fights, such as overestimating himself and bragging about his numerous fights in the past, showing a bit of a boastful - albeit entirely warranted - side on his part.

Being the first Fang of Metsudo, Akira and Mitsuki are considered to be the best of friend's while in truth they don't like each other at all, Akira considers Mitsuki a rich boy that never had to work for anything in his life while Mitsuki considered Akira a beast with no brains. But despite this, they work together and seem to have a brotherly bond because even if they argue at the end of the day, they will make up and work together.
