After Raphael, it was archangel sariel's turn to tutor Rudra.
Sariel looked like a young man in his prime wearing a black leather jacket , white tshirt and blue denim jeans alongside some really cool aviators.
If he did not have the huge angelic white wings on his back , he could pass for some Hollywood movie star, however the wings made him seem even more of a baddie than a usual actor.
Sariel had an interesting past in the history that Rudra had learnt about the Archangel's , apparently Sariel for some time had left Heaven to learn among the human race about his station, this choice made Sariel more human (similar to his older brothers; Ozriel and Michael (to some degree) than his other angelic brothers and sisters.
He would learn that not everything was easy in life, Sariel worked with his own hands instead of taking the easy road. This shows more morality as Sariel would protect the children of sinners while other angels will kill all of them.
