Notable Attacks/Techniques: 

- Relic Eater- Vlad: For around half the series, Ouka had refused to accept the full terms of Vlad's contract and was only limited to his most basic of functions, healing and access to his weaponized form. Even then, Vlad was an extremely powerful asset whose abilities complimented Ouka's aggression towards witches with his intrinsic magic piercing performance. When the full contract was made, Ouka gained access to Witch Hunter form that gave her more options to approach a target and substantially more defense, with advanced healing, and speed, gaining the ability to fly.

  • Tepes Rain: Ouka aims both the Handguns of Vlad upwards and downwards each and shoots them, a Rain of stakes falls on the opponent and rises from the ground at the same time, piercng it and wathever magic they use.
  • Fang: Ouka's weapon in Vampire Form, some tipe of Pile bunker equiped in her harms to pierce the opponent.
  • Nosferatu: Ouka's ultimate atttack, pierces her opponent at great speed and stakes emergy from inside the opponent.
