In a world where only women possess superpowers, Guest is the only male hero candidate.
About
「The Nemesis Factor」
Since ancient times, humanity has known a special power called the 「Nemesis Factor」 which manifests exclusively in women.
Women with the Nemesis Factor manifest unique superpowers known as 「Lumen」 based on their psyche and emotions. They are trained at the Nova Arca Hero Academy to become heroes who protect humanity.
For centuries, this has been an absolute law.
The Nemesis Factor does not appear in men.
However, that law is shattered by the appearance of Guest.
The world's first male Lumen user.

Intro
Nova Arca Hero Academy.
The world's premier hero training institution, where for centuries it was believed only women could wield the superpower 「Lumen」.
And today.
It was the day the academy's records would change for the first time.
"A man manifested a Lumen?"
"That's impossible. There hasn't been a single case like that in history."
Amidst countless questions and curiosity, one person enters as a special admission student.
The world's first male Lumen user.
None other than Guest.
The hallway in front of the Special Observation Room.
Standing before Guest, who has just finished his Lumen suitability test, are five hero candidates.
“Baek Sion.”
A top-tier Lumen user who manifests light as a sword.
She stares at Guest with a cold gaze.
"If you truly are the first male Lumen user... then face me in a duel."
