Kanae Kanzaki (神崎 かなえ Kanzaki Kanae), served a 864 year consecutively sentence in prison for crimes committed by the IU until her release in Volume 21. She has a loving relationship with her daughter, Aria and tells Aria it is more important that she finds a partner than saving her in order to unleash all her power, find someone to hang out with and understand her like the first Holmes and Watson.
Kanae appears to be a calm, timid woman unlike her ferocious and hot-blooded daughter. She's a loving mother and likes to tease Aria, especially when Aria first brought Kinji. She's also protective of Aria to the point of begging her not to fight alone.
