Adrien

Adrien is the younger brother of Anya. He is less than one year old, and has appeared in only one episode, but has been mentioned at least once in every episode since. ￼

Nothing is known about Adrien's personality but from Anya's description, Adrien looks up to her. This might not be true considering that he is still in early development stages. Maybe Anya thinks this is true based on how snowflake looks up to Elsia. She may also think that he will look up to Anya in the future.

Adrien has Brown hair like his grandmother queen Iduna but his is much lighter.

It is hard to see how he interacts with others, but he generally gets on with his family well, and plays with Snowflake even when he can't really join in.
