Raising a Wolf in the Academy

About ten years ago from now.
I possessed this body.
I still vividly remember the expressions of the people I saw when I first opened my eyes.

The memory of everyone in my sight looking relieved that I had woken up and asking about my physical condition is something I will probably never forget.
Although it was confusing to wake up suddenly, I felt somewhat reassured.
The fact that so many people were worried about me meant that, at least, I hadn’t possessed the body of a villain.
I thought that at least I wouldn’t die right away.
The first thing I did after that was gather information.
I had them report what had happened while I was unconscious.
Since this body had been unconscious for quite a long time, no one was suspicious.
Some people were even worried that I was getting to work as soon as I woke up.
Anyway. The body I possessed seemed to be that of a nobleman of quite high status, so I could easily obtain various information.
Among the information I collected, skipping over annoying things like international affairs and focusing on the important stuff:
That this was a so-called fantasy world, and
That there existed a magic school, or rather, an academy.
Academy.
What a romantic word.
The moment I heard those four letters “academy,” it became my number one goal in this world.
To enroll in the academy by any means necessary.
Fortunately, with this body’s specs, enrolling in the academy was as good as done—
“What? Academy… But sir, your age…”
“Ah.”
—or so I thought. Unfortunately, it seemed that this body’s age was a bit too old to enroll in the academy.
There was almost a commotion about whether I had amnesia since I couldn’t even remember my own age, but I was barely able to brush it off as a mistake made shortly after waking up.
Just as my first goal in this other world was about to crumble, fortunately, there was no age limit for professors.
After several years of backbreaking effort:
“This concludes today’s lecture.”
“””Thank you for your hard work!”””
“Thank you all for following along with the long lecture.”
I was able to become a professor at the academy.
