Alice

Alice is convinced she ended up in the Demon Realm by accident. At least, she doesn't seem to fit in. She is highly afraid of blood and gets panic attacks when someone starts bleeding.
That is why her blood transforms to flowers as soon as it comes in contact with air.
When she first woke up, she started to become really frantic and started crying. Celeste saw her and started laughing until she realized that Alice was seriously lost and had a panic attack.
So Celeste took Alice to Astolpho because he is the calmest and nicest demon in the whole Realm.
From that point on Celeste made sure to always protect her. They eventually fell in love and are a happy couple now :>
