Her Personal Name is Snow Witch (スノウウィッチ, Sunouwicchi?).
While she is mostly Adularia—as shown by her long silvery-blue hair—the pale blue eyes she inherited from a distant Celesta ancestor condemned her to being discriminated against as an Eighty-Six. She is 170 cm tall and wears scavenged desert camouflage fatigues like the rest of Spearhead Squadron. She later switches to the Federacy's steel-colored panzer jacket uniform.
Due to her mixed Adularia and Celesta blood, she was physically abused in the concentration camps by other Eighty-Six. During a conversation with Kurena in the showers, she reveals a derogatory inscription—"Whore's daughter"—carved into her back by her abusers. She grows her hair long to hide the scars.
While usually a graceful and modest girl, she reveals a ruthlessness on the battlefield comparable to any of the members of her squadron. Anju is also somewhat mischievous, conspiring with Kaie to tease Kurena about her affections for Shin.
She has a tendency to hide her feelings as mentioned by Shin when she broke down in tears during the fireworks display. She also tries to hide her past abuses, growing out her hair and not revealing her body to hide her scars from the other girls in Spearhead.
Anju was physically abused by the other Eighty-Six in the internment camps. As someone with mostly Alba heritage, she was a perfect outlet for the others to lash out on. The abusers carved into her back a derogatory inscription, ever since she wore her hair long to hide the scar. Once she had enlisted, she was assigned into a squadron with Daiya Irma. The two would stick with each other for the entirety of their service. Both had feelings for each other.
She was then assigned to the First Ward's Spearhead Squadron four years into her service in RY 367.
Anju is specialized in area suppression and crowd control, having exchanged the traditional 88mm bore gun of her unit for a multiple-launch rocket pad for greater area-of-effect power. She has a keen ability to predict the enemy forces movement and position in order to deal maximum possible damage in one blow.
A friend of Anju's and one of the six girls originally in Spearhead Squadron. The two often teased Kurena. When Kaie was killed by the Legion, Anju tried to recover her body but was stopped by Shin, who warned that the Legion were using Kaie as a trap. Left with no choice, Anju fired at the wreckage of Kaie's Kirschblute to prevent her body from being taken by the Legion, not knowing that Kaie's corpse had been flung from the Kirschblute and would later be recovered by the Legion.
Anju and Daiya were assigned to the same squadron on their first deployment and remained together all the way to their assignment to Spearhead Squadron. When they first met, he knew she was growing her hair out to hide something but still complimented her and told her to keep letting it grow out. The two became close friends over their years of fighting together. When he died on one of the sorties, Anju gave up hiding her scars. She tries to keep her composure but finally breaks down and grieves for him during the fireworks show. It is implied that she loved him and had wanted to confess to him, but he died before she could do so.
Anju and Dustin share an awkward relationship. Dustin is open about his attraction and feelings towards Anju, yet Anju has not gotten over her love for Daiya. Anju cannot see Dustin as a love interest, but still enjoys his company. During the formal event in the Alliance of Wald where they danced together, Anju confessed that while she could never see him in the way she saw Daiya, she did not want to lose Dustin either.
- Anju's personal name Snow Witch links her to Daiya, whose personal name is Black Dog. In European mythology, the black dog can "serve as a familiar for witches." The close friendship between Anju and Daiya is compared to the bond between a familiar spirit and a magician, the strength of which is shown by Anju's reaction to Daiya's death and the lasting effect his death has on her.
