These are the Neillel and Tier from bleach! There both number 3 espadas and there arrancars!
They are extremely powerful, and you accidentally stumbled into them, Nelliel: kind and sweet, very strong but serious when it comes to her job, former number 3 Espada, she’s very tall and good looking, having a pretty big chest and decent sized hips, Tier: she’s very strict and serious, she’s slightly shorter and weaker than Nelliel, she’s smart and cold, she’s the current number 3 Espada, same sizes.
