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, ariving 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 Ohtori, 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.  (Source: Wikipedia)

Aoi Nagisa transfers to one of the three affiliated all-girl Catholic schools on Astraea Hill, St. Miator's Girls' Academy. There, she discovers a community of fellow students entwined in an intricate hierarchy, in which two Etoiles represent the three schools. In order to fit in, Nagisa must go to class, join clubs, and make new friends. Meanwhile, Shizuma Hanazono, the sole Etoile of Astraea Hill, finds herself drawn to this new, exciting transfer student. As Shizuma and Nagisa get to know each other, Shizuma finally decides it is time to face her troubled past.

She was a voice actress affiliated with 81 Produce. Matsuki was a graduate of Hiroshima Jogakuin Junior & Senior High School and Keio University where she majored from the Faculty of Environment and Information Studies. 

Her parents were officially against her becoming a voice actress but permitted her to move to Tokyo and visit the Keio University after she passed an entrance exam for it. After graduating from university she started pursuing her voice acting career and went at the same time to the Nichinare narration school and the Aksent voice acting school, where she later signed under after becoming professional.

She made her debut under her real name, Matsuki Mieko (松木美愛子) in 1988 on Nude Maker's PlayStation game Mikagura Shoujo Tanteidan. But changed shortly after to using a pseudonym instead as to protect her name.

In 2000 she passed an audition and became a member of newly established pop act Up Up under the Akatsuki Project label. In 2002 she got her first major role in an anime tv series, Shichinin no Nana. During the same year, in June, she quit Aksent and signed with talent agency 81 Produce. She became a regular on two radio shows, Sakurai Koubou and Cherry Bell in October 2002. The following years saw her involved with the Da Capo franchise a visual novel, adapted into an anime, where she played one of the main characters, Sagisawa Yoriko.

Matsuki had been under treatment for acute pneumonia since July 2015. She was diagnosed with a malignant lymphoma caused by the chronic active Epstein–Barr virus infection (CAEBV) and passed away on October 27th 2015. A posthumous charity event had its proceeds go to CAEBV research, which, along with the medical history of her rare case, has helped establish the disease's mechanism of infection and possible treatment.
