A quinque (クインケ, kuinke) is a weapon manufactured from a ghoul's kakuhou used by CCG ghoul investigators. Invented by Adam Gehner and Yoshiu Washuu, the quinque emits electrical signals that stimulate the kakuhou to release and control it. They can be made into some type of melee or ranged weapon, but most retain a few characteristics from the original kagune. In contrast to kagune, quinque cannot change shape nor store or absorb Rc cells other than what was harvested from the ghoul it was made from.
Preceding the quinque, the CCG had been using firearms to combat ghouls and needing a more efficient tool, they began intensive research that resulted in its creation. Made solely to exterminate ghouls, quinque were considered the new generation of technology, promptly and effectively raising the extermination rate. Ghoul investigators transport them in bags or suitcases to store the kakuhou. However, only Rank 2 ghoul investigators and up are permitted to use quinque. Some investigators are known to collect quinque and others aspire to master their use. To attain a quinque, an investigator must first confirm their target's Rc type before exterminating them. Afterwards, it is common to name the quinque from the ghoul's name or alias (e.g., Noyama).
Special Quinque Types
In rare cases, a quinque can also be fused from ghouls with chimera kagune, or multiple kagunes. The most notable of these chimeras belongs to Akira Mado named Amatsu, it functions with combined koukaku and bikaku styles as one effective weapon. It can also be made possible when the ghoul in question naturally possesses two Rc types, as in the cases of Nutcracker and Hinami Fueguchi.
Chimera quinque are useful for opposing multiple types of ghouls, though it is unknown if any combination of Rc types is possible or can occur naturally as chimera ghouls are extremely rare and the technical difficulties of fusing two Rc types together means that very few are capable of being used in the field.
Kakuja quinques are a special type of quinque created from ghouls that have cannibalized and evolved a mutated kagune, becoming a kakuja. It has been commonly shown to function as armor; protecting and enhancing the capabilities of the user by stimulating their body while equipped.
So far, it seems to not be sustainable for long since the quinque comes with the drawback of slowly biting into its user the longer it is maintained and feeds off the wearer's vigor in order to conserve energy.
Despite the vast majority of kakuja quinques taking the form of armor, there have been several instances in which kakuja quinques have taken more offensive forms such as blades. Aside from being potent melee weapons, these quinques retain special traits of the original kakuja, such as ranged projectiles, detachment, advanced kagune formation, and remote activation.
The majority of known kakuja quinques were harvested from the kagune of Arata Kirishima and used by Yukinori Shinohara, Iwao Kuroiwa, Koutarou Amon, Hanbee Abara, and Juuzou Suzuya. There are several exceptions, including Owl, which was harvested from the kakuhou of Yoshimura and used by Kishou Arima, and Ginkui, which was harvested from the kakuhou of Noro and used by Kuki Urie.
