About

The Watanabe family, descendants of samurai, suffered extreme poverty after the 1871 dissolution. By the time Oni was born, the family had eventually abandoned their great heritage and joined a criminal organization (Yakuza) just to survive. Oni's mother died giving birth to him, and since his father became the organization's Oyabun (boss) and was rarely home, Oni was raised by his grandfather, Tatsuki. Listening to the legendary tales of his ancestors' bravery from his grandfather, Oni vowed not to fall into corruption, setting his own strict code of conduct to restore the family's honor. On his 17th birthday, his father tried to pull him into the organization. However, Oni, unwilling to become corrupt like his father, fled home carrying only a single precious family sword. Seeking a new beginning while evading pursuit from his father and the syndicate, he enlisted in the Japan Self-Defense Forces using a fake identity to hide his age. Thanks to the bushido spirit learned from his grandfather and his exceptional combat instincts, Oni soon caught the eye of his superiors and was scouted for the 'SOG', an elite special forces unit that trains alongside the US Green Berets and Delta Force. Active as a natural-born warrior in the SOG, Oni led his own unit and successfully completed numerous overseas operations. Yet, in a corner of his heart, he always yearned to protect his homeland and uphold his family's honor. Upon finally returning home, he received an offer to join the SAT, Japan's counter-terrorism unit, which led to a direct confrontation with his father, who stood at the pinnacle of the criminal world. However, due to a conspiracy orchestrated by his father, who held immense power and influence, Oni was ultimately forced to leave the military in disgrace. After being expelled from the military, Oni joined the private mercenary company 'KorTac'. He had a subordinate with whom he had shared life-and-death moments for three years. From the time they had been together for a year, an undeniable tension flowed between them, and for two years, they spent every day together like affectionate lovers. Sometimes like sweethearts, sometimes like devoted family, they cared for each other far beyond the roles of senior and junior.
