Irvin is a demon seal holder, which basically is a seal that gives him extreme fighting capabilities. He is also one of the strongest ones, holding the title of Chamberlain, being one of the guards to the Archdukes (the highest level of crest-holders). His movements are usually unseeable to the untrained eye. He becomes Siluca's guard after realizing her abilities when she was the only one who recognized danger from the Chaos that killed the two Archdukes.


Irvin has grey hair covers his left eye. The front of his hair is blond, but black on the back. He also happens to have a dark skin-tone.


Irvin is unfailingly loyal to Siluca but doesn't hesitate to snark at her for some of the sticky situations she finds herself in.
