Rakuen no Bijo to Yajuu

From Kodansha: Young and rambunctious Belle insists on going out to play in the forbidden woods, but her adventurous streak abruptly ends when her mother is spirited away by a beast known to kidnap beautiful women. Twisted by the loss of his wife, Belle’s father keeps his daughter, who has unusual, violet hair, locked away in an effort to “protect” her from prying eyes. Finally emerging after years of solitude, Belle ventures back into the woods where she lost her mother and encounters the beast once more.
