After Reincarnating as the Demon King's Daughter

The angel Lanbai was on her way to spread goodness in the human world when she accidentally tripped. That fall sent her straight into reincarnation, and she was reborn in the Demon Realm by mistake. The retired Demon King looked at his newborn daughter and wept tears of joy. "What a beautiful child!" the Demon King exclaimed, moved. "Look, her pale skin foretells calamity, her blue eyes seem filled with evil thoughts, and her golden hair symbolizes drought and famine..." "My daughter is sure to become the most excellent, most villainous demon in history." Lanbai, who was still an angel at heart: "..." Aren't angels made of the most sacred goodness and righteousness? At first, the Demon King excitedly told Lanbai, "Sweetheart, come meet the seven most trustworthy demons under my command. Look! A few of them are your brothers, too." Five-year-old Lanbai was cradled in the Demon King's hands. She blinked in confusion, like a pretty doll. Back then, she didn't understand what was going on. Later... Greed: "She's my sister? Oh, she's mine, so everything she has belongs to me." Lanbai: "No, that's... You really don't need to take my dress..." Sloth: "Too much trouble." Lanbai: "I-is that why you took me home to sleep instead of going to class?" Gluttony: "Little sister likes strawberries!" Lanbai: "...You don't have to bring three hundred humans to the Demon Realm to grow strawberries, do you?" Lust: "Kids are no fun. Call me when she's grown up." Lanbai: "? [Danger]" Envy: "Demon parts for sale at low prices: fingers, tongues, eyes, and more. Or I'll give them away at random to anyone in need." Lanbai: "...Why do these parts look kind of familiar..." Wrath: "Didn't I fucking tell you not to trust the other demons?!" Lanbai: "Children shouldn't use bad words." Wrath: "Damn it!" Pride: "You should be grateful, because you've received the best love in the world." Lanbai: "You're right. Thank you, Daddy Demon King." Pride: "?" [One-on-one romance.
