Makai Ouji: Devils and Realist, Dance with Devils Recommendations
- main character is protected by a lot of handsome and strong boys
- set in a fancy school
- both have demons and supernatural as the main theme of the story
Both are shoujo series that involve otherworldly characters such as Devils, vampires, and demons. Both take place mostly at school as well. Dance with Devils is a reverse harem and involves more romance, but you could argue that Makai Ouji has a little bit too.
