Wild Rule (ワイルドルール, Wairudorūru?) is the proof of being the apex predator of the the Fang Clan. The true power of the Lord of the Black Dogs. One who protects the law of nature and enjoys its blessings. Said rule takes survival of the fittest as its main principle and asserts that it is only natural for the frail race of humans to be dominated.

| Wielding her own horn as a weapon, the Fairy Sword Galatine chews up the flesh of her opponents and converts it into power for Barghest. With each attack, she recovers HP and ingests the opponent's strengthening buffs, making them her own. She makes use of this ability to devour Ritsuka Fujimaru's Command Spells during the battle at the human farm west of Salisbury. |
