The Game of the Dead Souls

Being a genius in her past life, Sera died satisfied when she caused the downfall of her family, who had made her suffer her whole life. Who would have thought that she could have caught the attention of the underworld. They gave her a new chance in life, in a new world with a new name: Seraphine. But everything comes with a price. Waking up in the body of a baby, the small brain couldn't keep all the memories from stored. The reduction of brain cells from the brain of an adult with a fully developed brain to that of an infant was too great. So the baby girl kept crying, forcing the parents to take her to the Demon World, to the Demon King. The Demon King could identify what was wrong with the baby, but no one could help with that. So Seraohine had to grow up with terrible headaches until she reached puberty. But she was doted on by her parents and four brothers, the Archdukal family of the human empire.
