Although humanity tries to oppose them by releasing a large number of Ectis, a type of battle android, they are undeniably inferior to face the Fiaremu, which are over fifty-metres tall and overwhelmingly powerful.

In order to overcome this situation, the Japanese Diet makes the decision to use cell-growth factor CGF-3 technology, which enlarges living things, for military motives and send humans into battle as giant weapons.

Six heroines are selected as appropriate subjects for enlargement, and enter the specialist anti-Fiaremu unit, Ragnastrikers. These young women, trusting their bonds with the secret government agency, head into battle with their powerful enemies.

Ayano Anemori

Voice Actor: Tomoyo Kurosawa

Free-spirited and skilled at being spoiled. Her fault is that she’s a shut-in who loves her house so much that she never wants to go outside. She has a strong sense of justice and decided to fight Fiaremu in order to protect the world.

Moka Mihime

Voice Actor: Inori Minase

Pure and innocent, she’s the team mascot and is loved by everyone in the team like a younger sister. She’s aiming to become an idol and never misses a lesson. A cosplay maniac.

Izuki Kanomiya

Voice Actor: Maaya Uchida

The only daughter of the famous Kanomiya family. Her actions are that of a noble lady and she thinks she always has to be the best at everything. Brimming with curiosity and able to quickly take action, she’s also fascinated by the commoners’ way of life.

Hinata Toujou

Voice Actor: Mai Fuchigami

A ball of sunshine, calm and kind to anyone and everyone. She’s skilled in a variety of household tasks, but she’s always worrying the other members with her unique creative cuisine.

Kasumi Barnet Midou

Voice Actor: Aoi Yuuki

Kasumi is a former member of the military who applied to be part of the enlargement experiment but for some reason it failed and turned her into a 14 year old girl. She hates being treated as a younger person and she frequently gets angry. Her sense of responsibility and justice are stronger than others, and she gets angry at her fellow member’s slovenliness.

Nagisa Nanami

Voice Actor: Ayane Sakura

She may look cold but really she’s a pure and innocent girl. A late bloomer when it comes to romance. Everything she knows about love is from books or dramas, so whenever she’s alone with a guy she freaks out and ends up acting audaciously. A genius with an IQ of 200.
