Mato Kuroi (TV Anime Character)

Mato Kuroi is the main protagonist of the OVA Black★Rock Shooter. Her "other self" is the title character.

She is voiced by Kana Hanazawa.

Appearance
Mato is a black-haired school girl with blue eyes. She has short, choppy pig tails and wears a seifuku consisting of a white top with a dark blue collar and a dark blue skirt. She also wears black knee-high socks.

She is also seen to always have a patch of bandage on her right knee.

Many of her belongings, including her clothes, phone charm, and room decorations, have a star motif.

Personality
She is an innocent and naïve first year student in middle school. Outwardly, she is outgoing and excitable, but she is very awkward around people she does not know. Internally, she is sensitive and meek, but eventually learns to gain courage.

History
In her first year of high school, Mato comes upon Takanashi Yomi when looking for friends to make and decides to strike a conversation with her. Mato's bluntness and outward personality shocks Yomi initially, but the two become fast friends. They begin to turn to each other for everything, and Mato eventually shows Yomi a special place where one can see a large view, and gives Yomi a cell phone charm with a star (identical to the one she has herself). Additionally, Mato's skill in basketball encourages Yomi to join the volleyball team.

Things change in her second year. The two are put in separate classes, and Mato finds and befriends Yuu from her class. Mato initially tries to get both Yuu and Yomi to be together with her at the same time, but ends up spending more time with Yuu. This makes Yomi feel "left out" and causes the rift to increase.

Mato starts to worry about Yomi, but things get serious when Yomi completely vanishes, not responding to any calls or texts. Initially Mato believes this means Yomi is avoiding her, but when two men come to her house asking about Yomi's disappearance, Mato breaks into tears and continues halfheartedly searching for Yomi.

Eventually, Mato gets a mysterious text from Yomi with nothing in it. Convinced that this is a clue, Mato runs out of her house (wearing a black jacket with a star on the back) and rides her bike up to the place she showed Yomi. She finds the phone charm she bought for Yomi and holds it to her chest, finally realizing what Yomi means to her. This action gives her "other self" in the other world, Black★Rock Shooter, the strength to fight against the Dead Master and purge her from Yomi's body.

A light erupts from the charm and envelopes her, transporting her to a strange place filled with light. She meets Black★Rock Shooter there, and reconciles with her "other self". The two merge and both identify herself as Black★Rock Shooter.

In the end, a reconciled Mato and Yomi walk home from school; however, Mato remains unaware that Yuu is in a dark state...

Trivia

 * Mato's surname is often misread as "Kokui" due to the fact that it would be the more common pronunciation of the kanji in normal wording: however, "Kuroi" as a surname is the proper pronunciation.
 * Mato has a younger brother named Hiro who appears in a few scenes.
