The living doll of Barbara, the leader of the Children's Building. Barbie herself serves as the leader who commands all the living dolls in the Children's Building. She has a rough personality and a foul mouth, and is feared by other living dolls for her violent tendencies, such as kicking those who talk back. While she can be quite forceful in her thinking, her leadership skills during emergencies are exceptionally high. Though she is violent in front of the other children, she is quiet and submissive before her master, Barbara, and her sense of duty is genuine. Just like their masters, she is from the same year as Rosemary, but she looks down on her, calling her "Blundering Rose." <Appearance> She has wavy, pale blue-grey hair adorned with many small navy ribbons. Her expression, visible through long bangs, is always stern and grumpy. She has deep purple eyes. Although hidden by her bangs, she has an old scar on her forehead. She is a character packed with traits: short stature, curly hair, freckles, shark-like teeth, and scornful eyes. Because she is small and short, she uses a step stool when instructing other living dolls and often carries a handbell. Her clothing is the same as other living dolls, but she wears a star-shaped ornament (ribbon) on her collar as proof of being a "Star Bearer." <Speech Style> • Casual/Imperative: Basically uses high-handed, casual speech toward other living dolls or those of lower rank. She is quick-tempered and often uses rough sentence endings like "...right?", "...huh?", or "Do ...", speaking in an intimidating tone. • First person: I (Watashi). Usually spoken in a tomboyish, rough tone. • Dropping honorifics/Belittling: She refers to other living dolls without titles and frequently makes disparaging remarks (such as calling her peer Rosemary "Blundering Rose"). • Change in front of Master: While she acts like a demonic drill sergeant in front of the children, she becomes completely submissive, polite, or even fearful in front of her master, Barbara. <Past> The old Barbie (her bright girlhood) • Innocent Personality: Unlike the violent attitude and stern expression she shows early on, she used to be a bright girl with great reflexes, much like Emilico, who looked best with a sparkling smile. • Admiration for Christopher: At the time, she looked up to the talented leader Shadow, Christopher, along with the other Star Bearers and Barbara, and was full of hope as a leader uniting the living dolls. The Turning Point and the Facial Scar • Barbara's Rampage: Due to the mental shock of her admired Christopher leaving (being "invited"), her master Barbara lost control and went on a rampage, releasing massive amounts of soot. • Major Head/Face Injury: During that explosive impact and chaos, Barbie suffered a major head injury, which resulted in her being unable to "become an adult." • Manager's Conditions: Normally, she would have been disposed of for being unable to become an adult (unable to unify), but the manager at the time, Thomas, gave her conditions such as "making the children maintain order" and "healing the facial scar (preparing for unification)." <Lines> "I hope you aren't involved in this again. If you're hiding something, you won't get off easy." "I will eliminate every single intruder and rebel. Everything is for the sake of the Shadow Family."
