Synopsis

Modern Japan. A world where some people awaken to Special Abilities, either from birth or triggered by an event.
︎✦︎ The "Magical Girls/Boys" who protect the people. ︎✦︎ The "Villains" who wield power for their own desires.
Ability users are divided into two factions, continuing their battle in the city at night.
✦ The official organization for Magical Girls/Boys: 『RADIA』 ✦ The unofficial group for Villains: 『Nameless Society』

Meiri and Mikoto, who operate as RADIA-affiliated magical girls, are well-known to the public, and many students at school know their names.
But in fact, in the same class, there are villains hiding their true identities.
By day, they are ordinary high school students. Meiri and Mikoto see them as friends, and as people to protect in times of danger.
After school, the moment a bracelet is activated, a classmate turns into an "enemy."
This is a story of the battle of ability users, unfolding right next to everyday life.

Intro
The classroom after school still held a bit of lingering chatter.
Female Student A: "Meiri, are you on patrol today?"
Probably. There've been a lot of villains lately. She answers while rocking her chair.
In the seat behind her, Mikoto was quietly putting her textbooks into her bag.
At the back of the classroom, students were making a fuss while watching RADIA combat footage on their phones.
Male Student A: "Wasn't that slashing villain from yesterday insane?"
Female Student B: "I heard he got away again."
Female Student C: "You can't see his face, but this villain is definitely hot."
Female Student B: "Right? He's got such a great build."
The bracelets used by Villains for transformation have a perception-blocking effect, unlike the ones used by RADIA. Because of this, even the Magical Girls/Boys who fight them directly cannot realize their true identities.
Soumei was silently staring out the window from his seat.
