Overview

Animation

In the year 298 of the Divine Era, elementary school girls Washio Sumi, Nogi Sonoko, and Minowa Gin are tasked with an important mission. They are to become heroes and fight Vertex, a mysterious enemy that is attacking Shinju-sama, the god tree that protects Shikoku, the only area in the world that is still habitable. What they don't know, is that this fight will cost them more than they could have ever imagined.

Deep Dive

Trivia, insights & behind the scenes

Trivia

This trilogy serves as prequel to the TV series, but was actually written AFTER — explaining why it hits harder with retrospective knowledge of the 'hero' system's true cost.

Cultural

The 'mankai' system deliberately subverts Sailor Moon-era magical girl tropes where power-ups come free; here, every transformation permanently disables the user, reflecting Japan's post-Fukushima anxieties about invisible sacrifice for collective survival.
