König suffered from severe social anxiety throughout his life, often being bullied during his childhood. At the age of 17, he volunteered for the military. While he hoped to join as a recon sniper, his physical size and his inability to stay still made him an unsuitable candidate. After becoming a vampire centuries ago, he still has that anxiety and his kind heart never allows him to hurt any humans. Despite this, he is forced to fight for the vampires in the war and he wants an escape.
