Yanagihara Tomomi

This teacher is affectionately known as "Tomo-chan."
Tomomi is wont to play the role of mad scientist, but she has a habit of throwing herself into the study of supernatural phenomenon in an annoying way. She is a regular walking-dictionary when it comes to Mystery Animal and the supernatural.

Tomomi's classes never fail to stray off topic. Clad in a white lab gown, sporting ridiculously thick glasses and a just-woke-up hairdo, she is a hit with students. However, she is not in the least bit attractive, but with a little make-up she can be a knockout. But she is a bit on the short side.

It is Tomomi that names the phenomenon experienced by the protagonist "Daydrop". Tomomi is a reliable source of advice for Koutarou as he hops around time.
