Kuroi, Mother

マトの母

Black★Rock Shooter (OVA)
While she gets slightly more screen time than Hiro, her presence is not essential to the story.
She is first seen walking in on Mato while she is brushing her teeth. She is surprised to see her up so early and hopes Mato can keep up the routine. While cooking breakfast, she tells Mato to go wake up Hiro, and although Mato protests, she does so after her mother reminds her that she is the older sister.
When Yomi vanishes, Mother Kuroi calls Mato and tells her to call her as soon as she leaves school, as the police have come to question her about Yomi's disappearance. In this circumstance, she can only comfort her daughter, who cries for her friend.
