Abandoned by my parents, I was picked up by the head of an assassination syndicate and raised from childhood to be an assassin.

Assassination is never simple; it's a life-or-death occupation where failure means your own death.

Having survived over thirty years as a killer engaged in such life-or-death dealings, continuously taking lives, the mission assigned to me was—the assassination of the Hero.

Under the promise of retirement from this assassination business, I undertook the most challenging mission of my life… and successfully assassinated the Hero.

True to the promise, I was released by my adoptive parent and boss, the head of the assassination syndicate. However, my clothes were in rags, my hair was a mess, and I had only enough money to rival a child's allowance.

To make matters worse, having done nothing but assassinate since childhood, I had no social experience, and I was an old man nearing forty.

No money, no home, no job.

Though I was cast out into the world in an utterly hopeless state, to turn my past harsh, brutal, and hellish life into something I could look back on fondly, I decided to restart my life.
