HobbyFantasizing, daydreaming, reading racy material

MottoGo away dirty thoughts!

A member of Trinity's Make-Up Work Club. Koharu was originally part of the Justice Task Force, but she was forced to transfer to the Make-Up Work Club due to poor grades which put her at risk of flunking. A dunce who can't keep up with her classes despite thinking she's an elite student. Koharu reads racy material for fun, and gets dirty ideas from the most trivial things, which ends with her embarrassing herself.
