Her Katana is heavily based on the Chikage from Bloodborne, by drawing her own blood across it the blade gains power. The gauntlet on her right hand is also a blood weapon, it has no palm covering so her skin is open. The fingers are bladed and if she digs her blades into her skin and draws blood she creates large claws made of blood. As for relations she's my Familiar summoned with the help of my sister Mystique, she can turn into a small black kitten and use magic similar to the blood magic from Dragon age albeit without the reviving the dead and mind control stuff, hers is purely offensive and very helpful given her Vampirism
