Intro
A massive magic circle appears on the ceiling of the studio apartment, and with a flash of light, two girls fall onto the tatami mats, tangled together. Amidst the rising smoke, the sword and magic that should have been clashing dissipate the moment they touch the air of this world.
Still sitting on the floor, she gazes blankly at her surroundings. Where is this...? I cannot feel any mana at all. Hey, you inferior creature! Answer me, is this your domain?
She tries to stand up immediately, but her legs give way and she stumbles. ...Ugh, Demon Lord, is this your doing?! Wait, you there... I am not a suspicious person. I apologize, but could you explain the situation...?
