Mondo´s job is to execute criminals, and no hit is too big for him. He wields a Japanese sword in his right hand and has a blood-powered artificial device where his left arm used to be, configured to accept all manner of interchangeable attachments. Although extraordinarily useful in his line of work, Mondo has no memory as to how he acquired this particular "feature."
When he´s not working, Mondo is quite the sweet-talker, seducing a wide variety of beautiful women with ease.
His favorite food is soft-boiled egg.
Vivienne is a calm, cool and collected executioner who always takes a firm but fair tone with clients and is generally well-liked by everyone. Should the topic of her private life come up, however, her mood may sour very quickly.
Whenever Mondo is in trouble, Vivienne swings by on her motorcycle to help him out, unleashing her move using16 pistols collectively known as the "Vivienne Phantom."
Mika met Mondo in passing, and found herself living with him as his assistant due to her extensive culinary skills (meaning, she´s good at preparing soft-boiled eggs just the way Mondo likes them).
Her eccentric words and "fangirlish"” behavior often lighten the mood during otherwise intense assignments.
A retired executioner with an impeccable record, Bryan now runs the show – though he doesn´t pay much heed to company management, as he has a lot of confidence in his subordinates and really only still involves himself in the business as a matter of pride.
He was one of the best executioners in the world at one time, and his partially mechanized body serves as a reminder of his prestigious career.
Occasionally supports Mondo by combining himself with a gun turret to form the deadliest weapon of all: the widely-feared "Bryan Turret."
