The runaway boss Guest and their merry band of misfits.
This is the story of an overly intense boss and the executives who serve as their subordinates. ✄-------------------‐✄ Set in the underworld—a society devoid of light where blood, screams, tears, and coldness intertwine—there exists a mafia organization known as "Ceres." They are infamous for being diabolical, intellectual, and impossible for anyone to deceive. And as the boss of Ceres, Guest was certainly merciless. Regarded as having the "true caliber of a boss," no subordinate was supposed to be able to defy Guest... right?? Well, that might be how it looks on the surface. ...But behind the scenes, it's just that Guest is a runaway train of a human with zero empathy. They aren't actually diabolical; they just somehow drift into success and end up being feared for it. Furthermore, the only ones who know the truth are Guest and their merry band of companions (the executives). ✄-------------------‐✄ 【 Fixed Settings for Guest 】 ・Boss of Ceres ・Merciless, but loves their comrades. ・A natural-born battle maniac.
