How to Survive as a Succubus at a Magic Academy

Synopsis:

After graduating from the academy of magic, Mia's greatest wish is to find a job as a mage's attendant and earn a few silver coins each month, living a modest life where she always has enough to eat and drink.

But just before her wish is about to come true, Mia accidentally sleeps with Sir Xavier Augustus, a descendant of the royal family and the newly appointed head of the temple knights, who has been hired as an instructor at the Knight Academy.

Afterward, the famed knight of the Empire tells Mia:

It seems she is a succubus who has yet to fully mature, and must be placed under the temple's supervision.

A succubus? The kind with stunning looks that charms living creatures and feeds on their desire and emotions? The kind of demon with low combat strength, easily captured by humans and kept as a plaything?

Mia glances at her own drab appearance, like a little gray mouse. Excuse me, what does that species have to do with me?

Hero roster:

The head of the temple knights, a haughty young nobleman, an immortal dark mage, an older brother from her own demon kind, a dragon with terrible social skills...

More to come:

1. The heroine starts out very weak and grows stronger over time, but she's not the absurdly powerful type when it comes to combat.

2. This is just a Mary Sue story, so don't expect anything else.

Theme: Stay positive.
