Hikaru is the current leader of the Eiken club. She has black hair.
She was formally the head of Zashono's supernatural club, but only because every other member had graduated. She wears a lot of bandages to hide the wounds caused by her fainting from anemia. She was originally part of the committee set up by Cho Ginten to disband the Eiken club but soon found herself joining it and becoming the club president all in one go after Kirika Misono declared the next person to walk through the clubs front door would be the president. Hikaru like every other female character seems to have feelings for Densuke.
