Black☆Star's Mother was the unnamed mother of Black☆Star and a member of the Star Clan. Thirteen years prior to the start of Soul Eater, she, along with the rest of her fellow clan members, were slaughtered by DWMA.
She was known to be an individual who would do anything for money, much like the rest of the Star Clan, and had no qualms about taking the lives of others for her own personal gain.
Not much of her has been seen. She wore clothes similar to that of her son Black☆Star, outfitted with a sleeveless shirt and bandages around her waist. She also wore black trousers that were partially white. She also sported a bandana around her head with some of her hair protruding out. She also wore some sort of gauntlet-like device around her wrists which sported her chain weaponry.
Not much is known about the abilities Black☆Star's mother possessed. It is known she was able to use some sort of chain-like weapon and was infamous enough to get notoriety along with the entire clan. However, she was no match for DWMA's forces. Due to the Star Clan coming from the Hoshi Family's Dojo, it is presumed that she also skilled in the Hoshi Family's Martial Way.
Thirteen years ago, Black☆Star's Mother was among the Star Clan, terrorizing various villages including the Needle Village. At some point she had Black☆Star, whom the father was White☆Star. She would later be slaughtered by DWMA forces along with the rest of the Star Clan for her crimes.
