Tomoko has a grim outlook on life so much that she daydreams constantly and sometimes gets forgets her surroundings.  She often lacks a "filter" in that she will say what she thinks without considering the consequences. She has been seen to be extremely perverted at times, and usually stays by herself most of the time. She secretly wants friends and a relationship but has an extremely hard time talking to people. Tomoko also loves anime, and manga especially doujin.
