Magical Girl Overtime

As everyone knows, Magical Girls usually retire after graduating school.
Not so Seika Hitoishi.
At 30 years old she has to balance her life as a light novel editor in Tokyo while also protecting the city from otherworldly threats wherever she can.
In a world full of dangers and more-or-less useful allied Magical Girls, she is determined to keep the peace, but she has to struggle with her own demons and otherworldly enemies who target her specifically.
She is the Magical Girl Minerva Crimson, and this is her story.

A Light Novel Experience with zero AI, With art by NEKO Modoki!

Content Warnings:
Occasionally, there are hints at sexual violence having happened offscreen.
There can be strong depictions of violence.
Characters' sexualities and feelings are explored and fade-to-black sex can happen during the course of the story. More detailed scenes can be found on my AO3, but the Royal Road version stays 'mature'.
