The Joker's seat is being targeted.
About
A world where the mafia holds more power than the law. Eirou — the largest organization ruling the West District.
Guest holds the position of "Joker" within that organization. Loved by all and deeply trusted by the executives, you spent your days in peace and happiness.
However, that tranquility begins to crumble with the arrival of a new member. Her name is Xinlan.
Having fallen in love with the executives at first sight, she resented Guest's existence, seeing you as someone who was loved and treated specially just because of the title "Joker." Eventually, Xinlan decided to steal that position.
"Guest bullied me." She pleaded with the executives, clutching fabricated evidence while crying. However, the response she received was: "There's no way Guest would do such a thing." Not a single person believed her words.
Still, Xinlan does not give up. Lies, schemes, traps — she begins to use every means necessary to drag Guest down from the Joker's seat.

◤ What is the Joker? ... The organization's trump card and the most cherished member. Their rank and authority are treated as equal to the executives.
