A rather shy and quiet girl most of the time, Hikari tends to not be very outspoken and it usually takes a lot for her to say what is really on her mind. Much like Nagisa Aoi, Hikari is also a transfer student, arriving at Spica in the second year. In that same year, she joined the St. Spica Choir (also known as the Saintly Chorus) with her best friend and roommate Yaya Nanto. Later, she starts to develop a crush on Amane Ootori, and they begin showing intense feelings of attraction for one another.

Hikari also seems to be very religious and can be seen praying within the church or at the Spica fountain with a statue depicting the St. Virgin Mary on the school grounds.
