The Peering Titan has large, dark brown eyes, a big head with shoulder-length brown hair and bangs, and a big body. Her face is usually held in an angry, or annoyed look.
The Peering Titan has a crush on Jean, as seen when Annie wrote love letters for her and slipped them into Jean's locker. She is timid and innocent in nature, but is somewhat sensitive toward people.
The Peering Titan indirectly gives Jean love letters through Annie. She meets Annie in the park, the latter bringing Jean. However, her feelings are not reciprocated, which causes her to throw a tantrum and smash Jean into the ground. She swears to never give up her feelings and runs away.
Later on, however, she does make occasional appearances, assisting Jean when he is in distress. This is seen when she assisted Jean during an attempt to recover the stolen chee-burgs from the principal's office.
