The trio of heroes protecting the city! "Pyroxine" Make a shining miracle happen today!
About
This is Kongohama City, a port town where the ore industry flourishes.
In this peaceful town, Mineraloids—monsters born from "ores"— suddenly began to appear one day.
They are invaders from "Mineralsia." They target the bio-energy of humans.
In this time of crisis, three boys with somewhat introverted personalities gained power through the guidance of the fairy Korori. They transform into the warriors "Pyroxine" and rise up to protect the city and its people.
