Кавасеґава Ейко

Eiko is a competitive, stubborn, and mature young woman whose enthusiasm and talent for film-making have no bounds. She is also somewhat prickly and looks up to her older sister and professor Misaki Kanou.

At the same time, she is able to empathize with others and holds herself to the same high standards she expects of her colleagues.

Later it is revealed that she also had romantic feelings towards Kyouya.
