Amy

The only child between Beelzebub and his Queen Consort, Oriax. Because of the circumstance of their birth, Amy has no true form. As a formless Abyssal, they were gifted a custom hand-crafted doll to inhabit. Despite now having a physical presence, any mention of Amy outside of Beelzebub's court is forbidden. It's led to the belief that Oriax cannot procure children due to her being an Abyssal. While this could be seen as a sad existence for Amy, it's allowed them to traverse the surface world free of worry.At the start of the demon uprising, Amy took to hiding their presence on Earth. Demons so far haven't broken through any of Hell's Gates. It's unknown where they reside, but it keeps them safe as they sometimes enter slumbers that allow their formless self to visit Hell undetected. This is how they approach promising champions.Although Beelzebub is more than capable of directing champions on their missions, Amy offers more clues on how to complete certain tasks. Such as with Aspects. Majority are well hidden with Beelzebub only having vague ideas of where they are. Considering that Amy is a formless Abyssal, this has given them an advantage of gathering intel on behalf of their father. They can reliably direct champions to lost Aspects, but she never said anything about ensuring their safety going after them.
