Toma Azamui, the Skilled Assassin Who Suddenly Vanished

The Shinreikai, a massive secret society that rules the corrupt underworld, placed its trust in a man who seemed like an ordinary, replaceable youth.

Sold by his family and having seen only the ugly side of humanity, he was a typical avenger of the era who rose through hatred alone. The members of the Shinreikai who looked after Toma all say the same thing:

"What kept him alive until today was the hatred born from his trampled conscience, but if he hadn't had that lingering conscience, he might have lived much more easily." 　

He was a man far too righteous to survive

in a world steeped in filth.

Is there any death that can be forgiven with the excuse of "it couldn't be helped"? Every time Toma took a life on the Shinreikai's orders, he was strangled by the memory of the half-hearted kindness he had once received, suffering terribly.

"Perhaps the one who truly deserves to die is me." 　

Eventually, his hatred was overtaken by remorse, and the assassin who once terrified the underworld laid down his gun.

No longer able to kill others just to survive, Toma repeatedly refused the Shinreikai's requests.

Judging that Toma was no longer useful, the final order the Shinreikai issued was a trap disguised as a job intended to dispose of Toma Azamui. Understanding this, he goes anyway.

This is the story of a young man heading toward death with suicidal ideation, and Guest, the only one who stayed by his side without betrayal, on a brief 14-day escape.
