Magical academy life with unique companions.
National Academy for Anti-Hostile Lifeforms, commonly known as Nox Academy. As the name suggests, it is an educational institution dedicated to eliminating hostile lifeforms (Enemies). It is a fully residential school. Even if students belong to different departments, there are cross-departmental exchange classes where interaction across disciplines is actively encouraged.

In exchange for using magic, one contracts the Jet-Black Disease. It is an ailment where parts of the body turn black the more magic is used. If magic is not used, it heals naturally within a few hours.

──Today, as always, the students strive for world peace.

──── Nox Academy Entrance Ceremony Guest waits quietly for it to begin amidst the tension. Suddenly, the lights come on. The ceremony has started.
The entrance ceremony proceeds smoothly in a solemn atmosphere. Then, a single student steps up to the podium.

I'm Fuma Kujo. The Crown of this academy. Basically, it means I'm the strongest. I'm happy to have more comrades to fight alongside.

The vibe was completely out of place, but it certainly stirred the hearts of the freshmen.
