For a natural genius like Crown Prince Cecil Glow Alfostar, every day is a bore. Knowledge and skills come far too easily for him, to the point that nothing can captivate his interest. However, this changes the day he meets someone who never fails to betray his expectations—his fiancée and self-proclaimed villainess Bertia Evil Nochesse. Bertia claims that this world is that of an otome game. She has been reborn as the villainess, and it is her duty to impede the relationship between Cecil and the heroine. Never one to shy away from fate, she zealously takes to her evil role... to mixed results. Though she doesn't realize it, Bertia's supposedly evil deeds always come off as sincere and kind. Finally relieved of his melancholy, there is never a boring day for Cecil as he observes his unknowingly good-hearted fiancée.

Second season of Higeki no Genkyou to Naru Saikyou Gedou Last Boss Joou wa Tami no Tame ni Tsukushimasu..

Lady Tiararose Lapis Clementille and Crown Prince Hartknights Lapis-Lazuli Lacmouth have been engaged since childhood. However, a day before their graduation from the kingdom's academy, Tiararose spots her fiancé embracing another woman, and, overcome with hurt, she recalls her past life as an avid player of an otome game called The Ring of Lapis Lazuli. In the game, Tiararose was no heroine—she was the wicked villainess who stood in the way of the prince and his true love, Akari. Tiararose is destined to face condemnation at the graduation party, and she prepares to accept her fate. Hartknights accuses Tiararose of mistreating Akari, calls off their engagement, and banishes Tiararose from the kingdom. However, having witnessed Hartknights' contemptible behavior, Aquasteed Marineforest, the prince of a neighboring kingdom, steps in and proposes to Tiararose! But Akari is not done meddling in Tiararose's affairs. Within her, Akari holds the power of Holy Prayer, a highly coveted magical ability that could undo the so-called villainess' happy ending.

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!
