Rikka, Chiyo, Sekine and Tsubasa seem like regular middle-school girls, but they all have their own secrets.

Chiyo, despite her normally calm demeanor, is easily worked up. Cute things make her pull all-nighters to pursue cuteness. Ninja-related things remind her of her ninja upbringing.

When visiting a local street food vendor who just can't read the room, Rikka is forced to reveal several new powers that are only mildly threatening to the entire human race.

If you could make a wish come true, what would it be? Change the past? Change your gender? Lose weight? Whatever it is, Colonel Rikka has you covered. She just won't warn you beforehand.

After some ups and downs during the final exams, it's off to summer vacation at the beach. Great weather, great food, and great excuses for excessive self-defense await!
