Orphaned at a young age, Daigo has had the responsibility throughout most of his life of raising his younger sister Akira. He takes this responsibility very seriously, much like he takes all other responsibility seriously, and indeed pretty much all things serious, period. Daigo is pretty much the definitive example of an “upright man”. In fact, Daigo found himself drawn (against his will) into a battle to pacify the gangs of Gedo High School and surrounding areas. The primary gang of the time, the Rampagers of the Wind, were cruel and stood for nothing but their own petty ambitions. With his incomparable martial arts skill and unflagging personal sense of justice, Daigo and his allies defeated the former gang and reformed all the delinquents into a new gang that is sworn to protect the peace and justice of the city with their fists. Yes, he’s that upright.
It was during those time that Daigo drove his motorcycle and wore the skull-emblazoned helmet that his sister Akira now wears. When a series of mysterious kidnappings occurred, Daigo investigated the matter itself, preferring not to involve others in the battle. This proved to be a mistake, for Daigo suffered the first defeat of his life at the hands of Hyo Imawano, the architect of the kidnappings, who subsequently brainwashed Daigo into being his servant. He was rescued from this predicament by the actions of Akira and her newfound friends, but was disturbed that weakness had been exposed in him, and subsequently went on a training trip to reevaluate himself and his notions of manliness.
Daigo is, well, to put it bluntly, a phenomenal badass. One of his favoured training techniques is to stand in one spot and let Gan or Edge attack him with all their might. He neither strikes back nor moves from the spot, and Gan and Edge generally collapse before he does. In addition, the force of his aura is so terrifying that lesser opponents are often too intimidated to attack, instead surrendering or running away. Even those that do force themselves to attack him often find his aura, as well as being frighteningly powerful, also can burst into searing flame. In strength, skill, speed, toughness, and any other criterion worth mentioning, Daigo is a formidible opponent, and most of his gang members hold him in justifiable awe. Daigo never uses weaponry, believing such tactics to be unmanly.
