Tsubaki is a young bespectacled woman with long straight black hair that extends all the way down to her knees, with split bangs and heterochromic eyes, with a violet left eye and a light brown right eye (both light brown in the anime).
In addition to wearing the Kuoh Academy girls' school uniform, she also wears blue, semi-rimmed glasses with square lenses.
Like Sona, Tsubaki has a serious personality and is rarely seen smiling. She also cares deeply for her teammates and is very loyal to Sona. However, ever since her fight Yuuto Kiba, she began falling in love with him, which causes her to be very shy and flustered when around him to the point where she loses her usual calm demeanor. She is noted to like younger boys who would make her serious, making Yuuto a match in a sense. She is shown to be quite sensitive with regards to her feelings for Kiba and his friendship with Issei, as seen when she begged Ravel to stop reading out the manga based on Issei and Kiba.
Tsubaki was born in the Shinra Clan which has an ancient and honorable origin that purifies evil spirits, but due to her trait that calls out to abnormal beings through her mirrors, she received a state which was basically isolation from the other members. She eventually overcame that by becoming a Devil under Sona and changed the mirror to her own powers, which became her Sacred Gear; Mirror Alice.
