Hayase Nagatoro

Height: 150 cm (4'11") A high school student that can suddenly pop-up anywhere and anytime. She is always crazy about her Senpai. She seems to be a member of the Swimming Club. Nagatoro is an energetic, athletic, popular and rather sadistic - but deep down very sweet - girl, often referred to as a "sadodere". She is part of a 'cool kids' clique together with her friends Gamo-chan, Yoshi and Sakura, and is a member of the swimming club, despite also having a liking for martial arts such as muay thai, boxing, capoeira and especially judo. ~!Chapter 81 — there's major development between Nagatoro & Naoto which reveals that Nagatoro is supposedly interested romantically in him and sets out a dare to get a kiss from him as a reward for beating her judo rival Orihara!~
