The Most Heretical Last Boss Queen: From Villainess to Savior

Pride, an eight-year-old first-crown princess, suddenly regained her past life's memories when she was 18 years old. Realizing that she is now reincarnated as a villainous princess of an otome game, the world she is in, she strived and resolved to atone for her game self's sin, as well as avoid the tragic events that would happen to her country-changing the world's story.

Pride warmly welcomes Stale, a boy from a commoner background who becomes his brother-in-law. As he becomes hateful towards himself in the game's original scenario, Pride immediately starts to take action to make him happy. Thanks to the help of her father Albert, Freesia's Kingdom royal consort, trust was established between the two of them.

Three years have passed since Pride regained her former life's memories. The tragedy that's supposed to happen during that time has been averted. The eleven-year-old Pride is living in peace with Stale and Tiara. However, upon realizing her own Last Boss Queen cheat, Pride becomes more worried that she is heading to the worst possible future like in the game.

Pride sets out on the battlefield herself to save the knights from a surprise attack. She puts her last boss cheat ability to use and defeats the enemy in the blink of an eye. She successfully rescues Roderick and his troops, who were destined to die in the game's original plot. Later, Pride and Roderick arranged a meeting regarding that incident.

Arthur declares royalty to Pride, who saved Roderick, his father, and decides to become a knight to protect her. As he immediately begins training, he shows glimpses of his talent in swordsmanship. Meanwhile, Pride, who has been troubled by the game's events as well as wondering about Arthur and Roderick, goes to the knights' training grounds along with Stale and Tiara.

In the game's original plot, the villainous Queen Pride repeatedly uses the law to her advantage and commits atrocious acts. 11-year-old Pride tries not to make the same mistake as her, and studies hard to administer the law correctly.

After two years of training to join the Knights of the Kingdom of Freesia, Arthur successfully passed his entrance examinations. At his knighthood ceremony, he once again pledges to protect Pride for the rest of his life. After such a happy event, Gilbert begins to make unsettling moves.

Gilbert has been working in the dark to find a special ability user to cure his fiancée, Marianne, from illness. Gilbert, who's betrayed the royal family for his personal interest and damaged Pride's name, angered Stale thus immediately tries to condemn him. Pride, who remembered the game's original plot about Gilbert, restrains Stale from doing so.

Arthur passed the terrific selection rounds and became Pride's Queensguard Knight. Pride, Stale and Tiara were jubilant at the result. Later, after completing their official duties, they made their way back to the castle, only to find Val lying on the ground.

Val burst into tears as he learned about his true feelings for Sefekh and Khemet. Seeing him like this, Pride, Stale, Arthur, and Gilbert, set out to rescue the two captives and eliminate the human trafficking organization. With Gilbert's age manipulation, they infiltrated the enemy's den in search of Sefekh and Khemet.

Despite being trapped at first, Pride and her party managed to subdue the enemy through superb coordination. They then tried to escape as quickly as possible, but news arrived that Sefekh and Khemet, who were looking for Val, had jumped into the cave. So, Val, as well as Pride and her party, rushed to them as the cave began to collapse.

After solving the human trafficking case, Pride returns to her normal, peaceful life. Val, Sefekh, and Khemet begin working as the royalties' official postmen after the incident and lead a more fulfilling life than before.
