Quinn Garland
Quinn Garland is the "Special Attacker" of the Grendel family. She wields the straight-sword-shaped Divider-VG4 as weapon, which is a Replica Divider provided by Vandein Corporation. She can attack at an indefensible speed by making use of energy particle attacks with her Divider. Her (Replica) Reactor is in-built, hence her React is through blood authentication.
