A timid male college student is reborn as a Tokyo beauty and forced to become a monster so he can infiltrate the magical girls.
Magical Girl Dark Moon, Kamihara Yu, ready for action!
He thought it would be easy, but things only got more troublesome.
The five magical girls who seem to stand for justice all hide darkness beneath the surface.
The sunny, righteous-seeming leader is a deranged sadist who can't control her urge to use violence against monsters and villains.
The pure and aloof student council president is actually a stalking creep who has a mad crush on the leader and gets jealous of anyone else.
The wealthy little princess of a corporate dynasty is a terrible brat who loves money and will even resort to scams.
The gentle, healing big sister with green hair is a pervert who's far too fascinated by pain, an S/M woman.
And last is a mysterious, morally ambiguous weirdo.
None of the five magical girls seems quite as righteous as they appear...
As the infiltration goes deeper, more mysteries are revealed, and Kamihara Yu finds himself with a new mission.
I have to destroy (save) them!
But the more time he spends with them, the more they start seeing him in a different light.
"New girl, I'm free tonight. Want to get some vigorous exercise?"
"I'm sick of the captain having you all to herself every day. Why don't I get a chance?"
"Those cheap gifts for ordinary people you gave me? I threw them in the trash ages ago! Hmph! It's not like I like them!"
"Kamihara, give me more pain. It feels so good, so wonderful. I want more~"
"You're such a cute little kitty~"
And so begins the romance (?): monster commander and magical girl.
