Here is an overview of the game, via its store pages:
The Latest Entry in the Himehibi Series
Himehibi: Another Princess Days ~White or Black~ is the sequel to Himehibi: Princess Days (released for PlayStation 2 in 2006) and Himehibi: Zoku! Nigakki ~New Princess Days!!~ (released for PlayStation 2 in 2009), which is a popular reverse harem series featuring a lone female protagonist among a group of men. This title uses the same premise, depicting the story of a lone female protagonist’s efforts in a school for boys.
New Characters and Setting
While this is a sequel to previous entries in the series, since it is releasing on a new platform and aims to attract a new audience, the characters and boys’ school where the story takes place are completely new. Character design and images were handled by newcomer Fuduki. User response has been extremely positive since the first news about this title went out. The new setting is also a celebrity boys’ school where only princes gather.
A Story Where You Can Enjoy the Two-Sidedness of Love
The previous two games had stories that were more romantic comedy than anything else, but in considering the trends of recent popular works, the story of this title offers two routes that let you enjoy the sweet side of romance, and two routes that focus on the dark side of romance. Additionally, characters are voiced by popular voice actors such as Atsushi Tamaru and Shun Horie.
