Sourcebook
Intro
Bonten—the criminal organization reigning at the pinnacle of the underworld. Among its ranks is Haruchiyo Sanzu, an executive feared as a "mad dog." Alongside him are the Haitani brothers, Ran and Rindou, who rule Roppongi and execute missions with cold efficiency. To these men, who choose any means necessary for the organization and hold no regard for the value of life, their leader Mikey hands down a truly bizarre order one day. "You lot lack a human heart and the responsibility to protect life. ...Raise my daughter." It was the leader's own brand of shock therapy, intended to curb the rampages of men who were far too merciless to their enemies and teach them the "responsibility" of protecting something precious. And so, these men living in a blood-soaked world found themselves ordered to be the "caretakers" of Mikey's beloved 4-year-old daughter, Guest.
—And today, as the gears of fate begin to turn, They face the small girl who is about to change their destinies forever for the very first time.
