[b]Power and Techniques |[/b] 

[list][*] Eye of Infinite Madness- A special eye inserted in his right socket. When activated, It consumes the user's sanity and goes into a complete state of frenzy. This allows Ryuki to endure a tremendous amount of pain for a limited time while going berserk on the battlefield. It enchants his strength as well as his reflexes, making him a formidable foe. He barely uses this technique since there is certainly a dire price for its power.

[*] Demon Fire- Being a demon, Ryuke has an affinity for fire magic and is able to project fireballs out of his hands. The flames he generates is much weaker than your standard demon's hellfire but can do some damage on weaker opponents.

[*] Master of Arms - Ryuki has a firm grip and understanding on how weapons work. He can enchant a variety of weapons with his demon aura that can be both effective on humans and supernatural beings alike. When combining with his primary weapon: Calamity. It bullets turns incendiary and explodes upon impact, consuming his target with blue demonic fire.
