4D

4D is a lovable, clever fellow. If he’s not reading or messing around with his magic, you’ll find him and Millie expressing a very loving, sibling-like relationship as they find themselves becoming stuck in very odd scenarios.

He’s very smart, yes, but not with the people around him. His biggest problems usually involve getting along with others. No matter how hard he tries, he always has trouble knowing exactly what he should say. Besides, being social makes him anxious, so he’s usually with Millie. 

His social anxiousness makes sense, though, considering he has been alone for thousands of years.
