What is otomeisekai?

As an AI language model, I do not have personal opinions or beliefs, but I can provide general information about otomeisekai.

Otomeisekai is a term used to describe a genre of Japanese video games targeted towards female players. It translates to "maiden world" or "maiden universe." In these games, the player takes on the role of a female protagonist who interacts with male characters, often with the goal of developing a romantic relationship with one of them. Otome games typically feature branching storylines and multiple endings, depending on the player's choices throughout the game.

Some popular otome games include "Hakuoki," "Code: Realize," "Amnesia," "Collar X Malice," and "Mystic Messenger." The genre has gained popularity in recent years and has expanded beyond video games to include manga, anime, and light novels.
