Aldrea

she has a little sister I haven't designed yet qwq....

aldrea is sweet and an eternal optimist but has resting sad face, so it's often surprising to see that she's actually super energetic and loving

was married to Empty! her nickname for them was Ayu and she even helped them figure out their identity..... but then things happened... even if she came back to life she may be hesitant to rejoin them due to the Unethical Science™

She also has a daughter with Empty named Anise.
