That version includes various Gainax references, such as the use of Neon Genesis Evangelion and Gurren Lagann costumes.

The game is set in modern times over eight (in-game) years.

Players take on the role of a parent – mother or father, in contrast to previous games in the series – raising a girl of royal descent, and a potential princess candidate.

Players must protect the girl after other candidates are killed and she could be the next target.

Players manage the girl's education, activities, and personal growth.
