Hard on the outside, and almost as hard on the inside, Ramiel is one of the warrior angels who is tasked with the hard job of leading wars and executing criminal Guardians.
Trainer to Julian, he has become slightly softer, his pupil having taught him how to care for people properly and with care as opposed to only conversing with other warriors. He has secrets he would love to tell someone, but his trust issues prevent him from opening up.
He cares about people more than he lets on, but it scared to show it due to losing someone dear to him in his past. That loss closed him off to others, and he refuses to show that side of himself to anyone but Julian, although it takes years for him to start opening up to Julian at all.
