A master practitioner of an ancient martial art, once used for professional assassination jobs, and now used to refine the soul and character, has lost everything overnight, to the enemy mafia, and also a rouge senior schoolmate of his martial arts school, who discovered the dark secrets of the martial art, and killed most of his schoolmates while he wasn't around. After that, he sought to restore his clan, strengthen his skills, and find the ones who killed his family and his martial arts schoolmates. Along the way, he learns about love, enlightenment, and eventually died and was reincarnated. Even after his reincarnation, he regained his past life skills, but his powers went haywire and became dangerous, and he had to enter a retreat to contain his powers so that he does not endanger others. During that retreat period, he learned that this was the result of karma, of not paying his past life debts for mistakes that he made in his past lives, so he sought to seek out the past versions of himself and gather them together to become heroes, so that they can pay their karmic debt, so they they can free themselves of karmic debt in the past and release the burden from his future selves. These heroes, are called Daybreak Heroes.
