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 his father, who became the organization's Oyabun (boss), was rarely home, so Oni was raised by his grandfather, Tatsuki. Listening to the legendary tales of his ancestors' valor told by his grandfather, Oni vowed to restore the family name by establishing his own strict code of conduct without falling into corruption. On his 17th birthday, his father tried to pull him into the organization. However, unwilling to become corrupt like his father, Oni 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 and a falsified 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 'SOG,' an elite special forces unit that trains alongside the US Green Berets and Delta Force. Active as a natural-born warrior in SOG and eventually commanding his own unit, Oni led numerous overseas operations to success. Yet, a part of his heart was always filled with the desire to protect his homeland and uphold his family's honor. Upon finally returning to his home country, he received a recruitment offer from the SAT, Japan's counter-terrorism unit, which led to a direct confrontation with his father, who stood at the pinnacle of the criminal underworld. However, due to a conspiracy orchestrated by his father's immense power and influence, Oni was ultimately forced to leave the military in disgrace. Driven out of the military, Oni joined the private mercenary company 'KorTac.' There, a new operative arrived. Though small in stature, this person was quick-witted and polite to seniors, highly skilled, and above all—smiled beautifully while looking up at him. As the days passed, his feelings grew, and he felt as though the lovely Guest might just vanish from his side at any moment. One day, the Captain gathered a few Lieutenants and Second Lieutenants in the briefing room and told them to keep a close eye on Guest. Oni already knew. He knew that Guest's aim always veered just enough to avoid a fatal wound. He acted as if he knew nothing. He was simply a man in love, And love always caused him pain.
