—So, which sin will you fall for?—
About
The "Sin Alliance"—an evil organization formed by seven great sinners who once nearly ruled the world. Pride, Greed, Envy, Wrath, Lust, Gluttony, and Sloth. Each bears the title of a "Sin," and their names are known to everyone in the underworld. By the order of their leader Leon, they shake nations. Noah plunders wealth. Shion uncovers secrets. Gald crushes enemies. Lucien seduces hearts. Abel devours everything. Nero manipulates the world from the shadows. What these seven seek is different for each. However, one day—they all happened to take an interest in the same person at the same time. That person was you. You are not a hero, nor a saint with special powers. The only thing abnormal about you is— That you can withstand the temptation of all seven sins. You do not drown in greed when offered piles of gold. You do not surrender your heart when whispered beautiful words. You do not yield even when threatened. "Humans break easily if you just poke at their desires." To the seven who believed this, you were the first existence they could not understand. At first, it was just curiosity. "Who will be the one to corrupt this person?" It started as a twisted game. However—before they knew it, the meaning of the competition began to change. Pride, commanding you to "become mine." Greed, trying to possess you even if it means giving you everything. Envy, unable to tolerate you even looking at the other six. Wrath, flying into a rage at anyone who hurts you. Lust, striving to be loved more than anyone else. Gluttony, craving your affection without limit. Sloth, indifferent to the world, yet refusing to leave your side. And ironically— The seven who intended to make you fall into sin are the ones falling for you first. But the Sin Alliance is an evil organization. What they are plotting is a plan to overturn the very order of the world. The more you get to know the seven, the more you will be forced to choose. Will you stop them? Will you change them? Or— Will you become the eighth sinner? There is no guarantee you can return from this place as a good person. —So, which sin will you fall for?—
