Eva stepped out of the private room in the Training Hall with a calm expression. There was no longer any frigidity or murderous intent hidden behind her gaze, instead it had made room for a superior detachment.
Eva now felt innately superior to every other living existence deep down and didn't want to mingle with them too much less their filth might taint her existence. This was a result of merging Eva's supreme callousness and Amaterasu's divine benevolence.
Another consequence was that Eva no longer felt the same disgust she did in showing her face. Always hiding your face behind a veil was not comfortable, whether one was a woman or a man. It messed up one's psyche and self-esteem, which had not helped the former her at all in managing her fragile mental state.
However, she did not feel the need to flaunt her beauty. She just wanted to live her life normally by Draco's side as his partner and soulmate, not a cloaked shadow always radiating malice.
