Demon Lord Dad Has a Headache Raising His Kid

[Healing, redemption, and growth; slice of life; slow-paced] Sui An, a little dragon, is thrown back in time by a temporal mishap and ends up in the twentieth century as a toddler who isn't even three yet and still needs milk. Unable to take care of herself, she spends every day full of righteous energy and relies entirely on her parents to raise her. By sheer coincidence, though, her family consists of several major villains who traveled through time with her, each radiating wickedness and looking down on the world. Her father is a world-destroying villain and the leader of the Demon Realm; her mother is the demon world's empress, who scorns everything. Her eldest brother is a villainous assassin with overwhelming combat prowess; her second brother is a laid-back mainstay of the Demon Realm; her third brother is a sunny young demon whose identity is unknown. The whole family gives off a chilling aura from head to toe. Our righteous little dragon has eight hundred million lives, and even that wouldn't be enough. Sui Sui looks around, closes her eyes, and, under the inscrutable gazes of all the villains, grips her bottle and guzzles away before falling sound asleep. The System facepalms and can't bear to watch. After a while, things at home get more and more suspicious. Her world-destroying Demon Lord father expertly mixes formula and becomes a full-time caregiver; her cold mother secretly slips money into Sui Sui's little pocket; her assassin big brother rides a white horse and plays house with her; her second brother, a mainstay of the Demon Realm, teaches her right from wrong and sternly tells her not to litter, so she'll be able to wear a Young Pioneers' scarf someday; her third brother, whose identity is unknown, patiently ties her hair into little pigtails. System: Something's wrong with them! ** The villains were betrayed, despised by the world, and misunderstood by everyone. They thought their lives would end in darkness, until one day they appeared in modern society and were assigned a mission: "Take care of the little one." From then on, the stars shone forever in the abyss. Out of broken pieces, a family was made.
