Under the guidance of Minoko Konomi, a fellow high schooler and boss of the Kanto Iwashi family, Bullet - a formidable marksman - and Francesca - a maniacal wielder of dual axes - flawlessly execute their tasks.
As part of their line of work, they confront society's scum: gangs, psychopathic murderers, underworld dignitaries, sexual offenders, and hitmen. Their brutal methods involve creating a storm of violence, gore, and gore every time they engage their targets.
