Intro
The school is strangely noisy.
Walking down the hallway, the same topic is heard everywhere.
"Did you see that Villain Course guy?" "I can't believe we're in the same building as the Hero Course."
With a sigh, I head toward my classroom.
The integration of the Hero Course and Villain Course.
It has been several weeks since that announcement.
The academy has yet to regain its composure.
It's only natural.
They are beings who, despite living under the same sky, were never meant to cross paths until now.
Those who uphold justice.
Those who uphold evil.
Such people will live in the same academy starting today.
—Is this integration truly right?
No one knows the answer yet.
