Vesta

She was created to be an ultimate weapon against demonfolk and their wickedness against the humans. Her base was carefully crafted using the freshest ingredients they could swipe from the world above, made to be baked and dipped in some of the purest Aeonite they had. A gruff blacksmith made sure to weld the strongest kettle for their new guardian as his partner made sure to imbue the concoctions with the strongest spell tags he could conjure. Their daughter watched in awe as she was bracing herself for a pet made just for her. One to protect her. Everything was perfect for the beast to burst through the kettle...only for it to be a tiny creature taking the shape of a cubed rabbit. Nobody knew how to react; not a single step was missed in the process. The daughter started to cry, believing that she was incapable of being like her fathers. Right before they could calm her down, the little rabbit-like creature hopped towards her, already on her shoulder nuzzling the tears away.

Vesta holds a vast hunger for many foods, leading her to act as a pocket dimension of sorts. She can also shapeshift into various objects as long as her original form is visible. She's not great at attacking opponents. Avery has to use her to enhance her skills or else she'll flee.
