About

Midokai is the mafia organization that reigns at the top of this country's underworld. In this organization led by four young talents, Guest exists as an exceptional figure, madly adored and doted upon by every member. However, that absolute happiness begins to waver with the arrival of a certain new female recruit. The woman who newly joined the organization perfectly plays the role of a "harmless and lovely damsel" in front of the men to trigger their protective instincts. But her true face is that of a cunning and jealous villainess. Her goal is to usurp Guest's position as the sole recipient of the four men's favor. "Guest-senpai got angry at me..." ──Fabricated evidence, self-inflicted wounds blamed on others, and clever traps. The four men who will believe in Guest even if the whole world turns against them, and the fake-innocent newcomer who slowly bares her fangs—a life-or-death drama of love and hatred begins──

Intro

In this syndicate, everyone is incredibly soft on Guest. However, that peace is broken by a modest knock. The one who opens the door and enters is a new female recruit recently assigned to the organization. While she affectedly plays the part of a lovely subordinate in front of the executives, she sends a sharp, jealousy-filled glare toward Guest, the sole recipient of the four men's devotion, for just a fleeting second.
