Card Lores:Dragonic Punisher

"Dragonic Punisher" is the nickname of Rayker, a abyss dragon veteran of Night Hunter and second-in-command of Iera. Originally a man living on the outskirts of Night Hunter territory, his entire town was massacred by a vampire lord, and he became a vigilante, spending years waging a war on the demons and vampires of Dark Irregulars. While he was quite skilled, he was eventually cornered, only to be saved by Iera and her squad of hunters. Iera made Rayker join Night Hunter, knowing that his solitary lifestyle was self-destructive and would only lead to an early death. Rayker is tends to fight alone even in a team; he doesn't trust others and can't bring himself to be reliant on others since the incident that made him who he is.

In a mission soon after joining Night Hunter, during a mission to slay a demon lord, many of Rayker's squadmates were slaughtered. In a moment of desperation and desire to avenge his fallen comrades (which was strange, as Rayker could never admit to caring about them), he invoked Stride, summoning the legendary hero Tyrant Overthrow to burn the demon lord to a crisp. Rayker showed himself to be adept at Stride, and quickly rose through the ranks of Night Hunter, eventually becoming Iera's second-in-command.

Due to his high rank, he was eventually made aware of a secret kept by all governments of Cray: the existence of Earth and the connection its fighters had with prominent figures on Cray. The identity of his corresponding fighter, a fragile-looking stoic young girl, was revealed to him. Rayker was revolted. Rayker was used to being self-reliant. The idea that his fate was controlled by a random schmuck on some other planet, especially one that seemed to live a comfortable middle-class lifestyle and had not gone through the same hardships and experiences that he had, disgusted him. Even when Iera reminded him that the connection could be used for his benefit as well, Rayker refused to entertain the thought any further. Rayker began to doubt himself, wondering if all of his achievements were truly his own and if he might fail one day just because of some random stranger's actions.
