Doctor Hashimoto

Doctor Hashimoto is the Guidance Counselor at Shermer High School. Very little is known about his reputation, accomplishments, and popularity among the students at Shermer High.

We know this because, at the beginning of the movie when we see the empty school (before the kids arrive) we catch a brief glimpse of Dr. Hashimoto's desk, and under his name it says 'Dr. R. Hashimoto, Guidance Counselor'. It is also implied Allison Reynolds sees him a lot. This is a nod to the film's production supervisor, Richard Hashimoto.
