Of all the classes offered at the Mage Society, his class is the least popular.
One of the Dimension Walkers who are shunned by the rest of the society,
he is as peculiar as the others of his ilk,
and while the others seclude themselves from the rest of the world,
too busy discovering facts about worlds outside this realm,
he publishes theses and lectures at schools on a regular basis.

But like I said, his class is so unpopular that only a few dimensional science nerds like me attend it. 
I don't think he hates us. We sure don't.

When he has no class or research project,
he would sit at his favorite corner in the cafe in front of the school and drink something
that I doubt is from the cafe's menu.
Whenever he does, he strikes quite a pleasing image.
Once I stopped walking and stared at him for a long time in spite of myself. 
Sometimes when our eyes meet, he would smile, and his smile is so otherworldlythat I'm stunned for a moment, by the intensity of the creepiness that is his smile.

When I found out he was also a famous adventurer, I got more interested in him,
but I didn't get a chance to get to know him better.
I found out about his sideline through the notice on the school bulletin board
stating that he'd resigned as a lecturer to focus on his other occupation.

I caught him leaving the campus, and he was with a silver-haired girl.
I assumed he was single. It seemed he wasn't. 
His companion had a charming, yet creepy mystique, just like he did.

They were bickering as they left.
She was complaining about something wasting their time,
and he was disagreeing with her, his face scrunched up in childish sulkiness that I'd never seen before.

I was curious about their relationship.
They could be boyfriend and girlfriend, or—who knows?—master and familiar.
I doubt it's the latter case, though. Most people who try to control otherworldly familiars end up mad.

Then again…

I can ask him about it when he returns, if he ever does.
I'm on my way to a classroom, thinking about him.
