RC Cells

Lore & Background

RC cells are a fundamental component of ghoul biology, flowing through their bodies like blood. A regular ghoul has a markedly higher RC cell count than a normal human, though the precise multiplier is not canonically fixed; these cells can become solid instantly, which is crucial for forming a ghoul's Kagune—a special predatory organ that can be manifested and used as a weapon during combat. The CCG (Commission of Counter Ghoul) uses knowledge of RC cells to develop technology for detecting elevated cell counts, helping them track and hunt ghouls.

RC Cells are a type of cell unique to ghouls that flows like blood and can become solid instantly. Ghouls possess several times the RC cells of normal humans, which contributes to their enhanced strength, speed, endurance, and regenerative abilities. A regular ghoul produces 4–7 times more kinetic energy in their muscles than a normal human. These cells are essential for forming a Kagune, a special predatory organ that ghouls can manifest and use as a weapon during combat.

The CCG has developed technology capable of detecting elevated RC cell counts to track and hunt ghouls. Consuming human flesh replenishes these cells, preventing starvation and maintaining power output. However, excessive usage or trauma can cause instability, sometimes altering physical traits like hair color due to extreme concentration.
