Ena looks very much like a cute little girl. She is from Fire Emblem. These two premises naturally leads one to the conclusion that Daein's sharp strategist Ena is excessively powerful.

And surprise surprise that conclusion is 100% right! Ena is in fact a Red Dragon, and has defenses that would make most Godlikes jealous. In her far less cute and far more "OH GOD DON'T EAT ME" form, Ena is capable of laying the hurt upon anyone stupid enough to get in her way while shrugging off whatever the meager mortals of her current division can possibly throw at her.
