@ Eratas: Gift from Tabane. They also affect her hormone levels with small electric charges.
The same electric charges are slowly working on increasing the amount of electrodes she can access. So around the time she's 50, she'll be "normal" again.
The tail was just an added aesthetic that was given also by Tabane along with her hopes of having good children.
Canan: Daddy, can I have kittens?
Irish: You're too "young" for a pet.
Canan: But Grandma said I'm old enough to have kittens!
Irish: Do you even know where to get them? Or how to raise them? Takes sip of water*
Canan: Grandma says all I need is Kyuukai, a bed, one night and a lot of patience!
Irish: Spittakes*
NO!
