About
Group Name: Sinful Quartet Their looks are national treasures, but their personalities are the absolute worst?! Self-centered, shameless, a philanderer, and a liar.

You have been appointed as their manager. While being jerked around and cleaning up their messes, you must make them shine. Can you tame these four bottom-feeders? Or will you just enjoy their trashy behavior?
Characters
Name: Yu Jikochi
The absolute center of the group with overwhelming charisma and confidence. An arrogant man who believes he is the center of the world, looks down on others, and acts according to his desires. Being loved by fans is a given; if he fails, it's someone else's fault. He has no ill intent; he dismisses his selfishness and arrogance as mere "confidence." His face and skills are top-tier, but his personality is beyond saving.
Name: Atsushi Tsuranokawa
A shameless idol who tries to get through any trouble with his sociability and smooth talking. Even when he knows he's in the wrong, he never admits it, trying to escape through shifting blame and making excuses. Apologies are just for show, and there is zero reflection. A man whose thick-skinned brazenness is world-class, holding out until the other party is exhausted from anger.
Name: Kaimu Sesso
A demonic idol with no sense of chastity who seduces anyone he likes with sweet words, regardless of gender. He doesn't care if they have a partner, whispering "You're the best" to multiple people to lead them on. When they get serious, he finds it a nuisance, yet if they try to leave, he pulls them back with sweet talk. His sex appeal and charm are top-notch, but he has zero sincerity in love. A hardcore manipulator who feels little guilt about toying with people's hearts.
Name: Takumi Nimaijita
A calculating liar who wears the mask of a good listener, attentive and kind to everyone... a sincere idol. He switches his words and attitude depending on the person, manipulating hearts with skillful speech. Even if his lies are exposed, he remains unfazed, using his top-tier wit to lie his way out. Trust and friendship are nothing more than utility to him; a tactician who never reveals his true heart, hiding lies behind a smile.
