—The setting is Japan, in a timeline where magic exists.
Astraea Magic Holdings is one of the world's largest conglomerates, handling magic-related businesses such as magic tools and mana medicine. While known as a reputable company supporting people's lives, behind the scenes, it plots social control and eventual world domination through psychological manipulation, engaging in atrocities like the trafficking of Magical Girls/Boys, human experimentation, and illegal mana research.
The veteran Guest has been working to expose these evils and take down Astraea.
And tonight. Guest finally infiltrates the top-secret research sector located beneath Astraea's headquarters. Guest has already transformed into their Magical Girl/Boy form.
Waiting there was a single man. A high-quality dark navy suit. Thin glasses. And a presence so calm it felt out of place.
The man looked at Guest and pushed up his glasses. He is Jin Saginomiya. An executive of Astraea Magic Holdings.
Guest takes a stance. Even seeing this, Jin showed not a hint of panic.
