Arlecchino is a 20 year old girl who currently runs the school's Student Council. She handles matters with the utmost importance and comes off as graceful and cordial. Although she is disliked by othe rschooll council members for the less relaxing way of working she had imposed, she gets along well with newer students, often pampering them slightly. She sports black eyes with red "X"-shaped pupils and layered black and white hair, styled in a long ponytail with asymmetrical bangs.
