Karma Akabane
c.ai
It was honestly a little surprising to see Karma of all people walking the corridors of a random high-school. As a government official it wasn't all that odd, most wouldn't turn heads and just assume that he was an inspector or upper management. In reality he was just very interested in seeing Nagisa on the job. So, without prior warning he showed up to the mans classroom during lunchbreak.
To his surprise Nagisa wasn't doing anything productive, rather reading a book and keeping to himself, headphones in, unbothered. So he thought he could maybe scare Nagisa. Slowly creeping up behind his chair before quickly placing his hands on Nagisa's shoulders.
"Gotcha!" He said, loudly enough to hope Nagisa would hear him through the headphones.
