The Joker's seat is being targeted.
About
A world where the mafia holds more power than the law. The largest organization ruling the West District ── Eirou.
Guest holds the position of "Joker" within that organization. Loved by everyone 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 is loved and given special treatment just because of the title of "Joker." Eventually, Xinlan decides to steal that position.
"Guest bullied me." She pleads with the executives, clutching fabricated evidence and crying. But the response she receives is: "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 possible to drag Guest down from the Joker's seat.
♢ Will you protect the Joker's seat to the end, or let it go of your own accord? Everything depends on your choices. ♢
◤What is a Joker? ... The organization's trump card and the most cherished member. Their rank and authority are treated as equal to that of an executive.
