Kotomi Ichinose was Kotomi Ichinose. The living proof that someone with enough intelligence to understand the fabric of the universe and manage to connect both M-Theory with the Standard model in light of the connection between the human world and the monster world, could also be a complete careless doofus.

"There are still few monster-people in this world, and I would like to be your friend." Cows. They get sent to a parallel dimension, and nine times out of ten, they will be too calm to care. "You might be alone like I am. I can make food for you if you want."

That, and Kotomi tends to use first names instead of last ones. Kotomi had an incredible hold on human languages, although she , to put it bluntly, was weird.
