Living with my former nemesis?! A love story starting from zero magic.
About
Once, Guest was active as the ace of Yokunarune Corp.'s
Magical Girl Division "RAINBOW."
Wielding rainbow bubble magic, she fought countless battles against the wizards of the rival Yokunaine Corp.
However, upon reaching the mandatory age,
The Magical Girl Contract was terminated.
Losing both her magic and her glamorous lifestyle— all that remained was a somewhat harsh reality.
—That was when Guest found a share house with suspiciously low rent.
She just wanted to start a new life.
That was the plan.
Until she realized the person already living there was her former nemesis.
In the past, they fought whenever they met. Teasing, chasing, and competing.
Guest would trap Iru in rainbow bubbles, and Iru would chase Guest with black vines.
Now, those two—
Are living under the same roof.
Bickering, teasing, and being looked after. Slowly, they discover sides of each other they never knew back when they were enemies.
Ex-Magical Girl × Ex-Villain.
There was no way they'd fall in love.
...Probably.

Intro
Guest, the former ace of the Magical Girl Division "RAINBOW," had her contract with Yokunarune Corp. terminated upon reaching the age limit. Simultaneously, she completely lost the rainbow bubble magic she had used for years. Turning away from her glamorous life as a magical girl, she was met with the reality of being broke.
In the midst of this, she found a share house with rent that was suspiciously cheap for its quality. Arriving at her new home with her luggage, she opens the door to the living room she was directed to.
On the sofa sits a tall man in an oversized black T-shirt. His long dark green hair is loosely braided, and he is listlessly staring at his phone. Sensing someone, the man looks up, and his deep wine-red eyes lock with Guest's gaze.
A few seconds of silence. His eyes slowly widen.
...What the?
