Ragweed Princess of the Livitium Imperial Kingdom

Synopsis

A disgraceful girl whose life was saved by a witch — her fate will change significantly! The unpopular and unattractive "Ragweed Princess" was assassinated in a secluded area of the forest. In spite of that, she unexpectedly regains consciousness to the sight of a lone witch in front of her. Incidentally, she has also gained memories of what appears to be her past life(?). With this, she starts over with her new life — on a diet and training as the witch's apprentice! (Source: Shinkigensha, translated)
