Noah Ararat is born into privilege as the 13th prince of an imperial dynasty and granted an existence most can only envy. After all, apart from the access to the empire's finest education and resources, Noah is a reincarnator with the memories of his previous life intact, blessed with an infinite level cap and an elite ability that allows him to utilize his subordinates' skills. Within the imperial court, however, status alone offers no guarantee of safety. While Noah's overwhelming potential sets him apart from his siblings from the moment he begins his training, it also draws the attention of nobles whose interests extend far beyond governance. Inevitably, Noah must learn to navigate the expectations of royalty and the mechanics of his unusual power, as he realizes that privilege invites control as readily as it grants it.

It is common knowledge that nobles will do anything for power; lying, manipulation, and extortion are the usual tactics. However, one family is exempt from this generalization: House Grail, whose main tenets are truth and integrity. The youngest daughter, Constance Grail, is just as moral as the rest of her family, believing in always doing the right thing and helping those in need. However, these ideals do not help her when her fiancé cheats on her with another woman. Framed by his lover in the hope of her downfall, Constance has no one to hear her pleas for justice. Everyone turns a blind eye, save for one—the spirit of the infamous Scarlett Castiel—who possesses Constance and turns the tables on her accuser. However, this aid does not come without a price. Ten years ago, Scarlett was executed for the attempted murder of Princess Cecilia. But this was actually a setup; as blunt and harsh as Scarlett could be, she would never stoop so low as to use poison. She has no idea who orchestrated her incrimination, but Scarlett demands that Constance—as the only one who can see her—help her exact revenge on all those who wronged her!

Ever since she was a young girl, Sooha was told to hide her superhuman abilities to avoid getting mistaken for a vampire. Having been accused of being one and blamed for her childhood friend's death, Sooha enrolls in Decelis Academy—a night school where supernatural beings, such as vampires and werewolves, allegedly cannot enter. At the academy, Sooha soon encounters Heli, a student who offers friendship despite discovering her secret. Heli introduces Sooha to his close friends—Jaan, Jino, Shion, Jakah, Noa, and Solon—who all have different powers as well. But their connection seems to run deeper than just that; they are curiously drawn to her, feeling as if they would do anything she wishes. In light of a recent murder that is said to be the work of a vampire, Heli and his friends' unsettling history slowly unravels. While the seven boys try to shield Sooha from the world of the supernatural, she inevitably gets entangled in the centuries-old rivalry between vampires and werewolves. As tensions intensify, Sooha realizes that she may be closer than ever to the creatures she hates the most.

All his life, Yuuya Tenjou has been the subject of resentment and contempt from everyone around him, even from his parents. To make matters worse, his grandfather—the only person who ever showed him affection—suddenly dies, leaving Yuuya truly alone. Despite facing many adversities, Yuuya does what he can to offer kindness to those who need it—but even the most good-natured people can only tolerate so much abuse. Just when he reaches his breaking point, a flicker of hope appears in the form of a hidden door in his bathroom. This door provides two-way access to an abandoned house in another world, where he instantly gains game-like stats and skills. Moreover, the house once belonged to a sage, which gives Yuuya access to remarkable weapons, equipment, and crops with extraordinary effects. With these newfound blessings, the once-undesirable Yuuya may just reach his true potential and become unstoppable.
