The Most Heretical Last Boss Queen: From Villainess to Savior (Manga) Vol. 1

This award-winning otome isekai series stars a final boss who decides to ditch the whole "villainess" schtick and use her powers to protect-not destroy-the people of her kingdom! Crown Princess Pride Royal Ivy is a monstrous little brat who, at the age of eight, suddenly realizes that she was a Japanese teen in a past life who has been reincarnated into her favorite video game! She already knows her future: she will rise to the throne as the Wicked Queen, destined to bring ruin and misery to all around her, until she is ultimately killed by one of her love interests. Pride decides that if she's destined to die, she may as well use her royal "last boss" powers to save everyone instead!
