Princess Heroine

At least one of the heroines in this VN is a western-style princess. Usually that means the daughter or a close relative of a ruling monarch.

Regarding her appearance she might wear gowns (though she might wear armor for combat, or a school uniform to fit in), and have a crown.

She does not need to be from the West as long as she fits the image (many fantasy princesses will be this instead of the Hime archetype).
