Kiriya Senshou

Kiriya was raised in a martial arts dojo along with three brothers. She brought shoujo manga for the first time in collage and was instantly hooked. But as she reads the love stories, she gets too excited and lashes out using martial arts, often resulting in broken walls. She also has the habit to toss and turn a lot while sleeping. Because of her stoic personality at school, she secretly feels pressured around the other students due to wanting to be admired and set a good example for them. After Koushi begins treating her as a girl, rather than as a tomboy, and offers his aid to her does she begin to grow feelings for him. This leads her to acting more embarrassed and girly like around Koushi. (Source: Megami-ryō no Ryōbo-kun Wiki)
