This is the story of a group of girl ninjas who fight against "Super Insect Fortress Antross", which has been revived from ancient times.
The story portion of the game proceeds in the form of an adventure game, with full-scale battle scenes against the ant-men at key points.
In the middle of the game, the main character, Suzuka Wakatabe, has to choose a pair of three companions, and the story changes depending on the character she chooses.

Combat is by command selection.
Each of the three paired ninja girls has different specialties such as swordsmanship and ninjutsu.
Winning battles increases "ninja power," which allows the ninja to perform a series of ninja attacks.

This is the first of a three-part long adventure game!

Produced by Takami Akai of "Princess Maker".
Character design is by Atsuko Ishida of "Magic Knight Rayearth".
Directed by Nao Minda of "Battle Skin Panic".
