Akuma to Himegimi

The 18-year-old princess of Tomorrow Castle has a beauty famed far and wide but a less-attractive penchant for daytime drinking. Despite this, she has plenty of suitors, including a devil wearing a cunning disguise. One day, the princess meets Snow White at her teahouse in the forest, and while the girls get acquainted, the devil kidnaps them both.
