Quinx

A Quinx (クインクス, Kuinkusu) is a human with a modified Quinque installed in their body. Because this resembles a normal Kagune, they are commonly mistaken for ghouls and half-ghouls.

Characteristics
Quinx are similar to one-eyed ghouls in that they only develop one kakugan, in contrast to normal ghouls who develop kakugans in both eyes. When activating the kakugan, the Quinx have a grey sclera in the affected eye instead of black like normal and one-eyed ghouls': it is unknown if this is due to Rc suppressants effects. Quinx can also digest human food and they do not crave human flesh like half ghouls and normal ghouls do. Even so, it is shown that devouring human flesh still triggers responses from their Rc cells, increasing the overall abilities of a Quinx.

Quinx are shown to possess increased physical traits similar to those of Ghouls, such as enhanced strength and agility, though this appears to vary greatly from individual to individual. A heightened sense (smell, hearing, sight) is typical, and healing abilities on par with those of a Ghoul are possible side effects of the surgery. Dr. Shiba claims that the more Half-Ghouls get hurt, (including the Quinx) the more their basic abilties will increase.

The Quinx Surgery was created after Ken Kaneki was examined by CCG after his capture.

Quinque Frames & Release
The Kakuhou that is installed into the body of the Quinx are modified through a process similar to the method used to create Quinques, believed to make them safer and seemingly allows the Kakuhou to adapt to the new host. This method involves coating the kakuhou in Quinque Steel, and then implanting it with a special system of "Frames" to regulate function and acts as a system of control. There are a total of five frames, with each subsequent Frame increasing or decreasing the potential output of the kakuhou by 20%. This process limits the potential strength of their kagune and restricts its form as compared to the highly-adaptable kagune used by normal Ghouls. As in the CCG, Quinx may petition their superiors to undergo the Release in order to put less restriction on the Kakuhou and require the signature of at least their acting superior or someone of higher rank.

The Frame Release is a surgical operation that members of the Quinx Squad may undergo in order to increase their viability in combat, rescinding one or more layers of Quinque Steel binding their RC cell output. This is most likely done by weakening or opening the layers coating the Kakuhou.

Trivia

 * According to Dr. Shiba, the starting point for the Quinx, in terms of Kakuhou regulation, allow for 40% of the kakuhou's potential output.Their frames start at F2, but there are experimental operations available to have it opened up more, though it is considered risky.
 * Dr. Shiba theorizes that the Quinx are able to eat human food as long as their RC levels remain below 1000, the minimal level for a normal Ghoul. It is unknown what would happen should they exceed this threshold.
 * The process of coating the kakuhou in Quinque steel may be to prevent the implant from converting the implanted individual into a One-eyed Ghoul by restricting contact with native tissues.
 * According to Sasaki, Quinx have enhanced strength like ghouls. This explains how Kuki Urie was able to kick Big Madam far away, and also pierce Tooru Mutsuki through the stomach.
 * Ginshi Shirazu has been seen able to jump high into the air and fire his Kagune projectiles. This could be enhanced agility.
