Ken Kaneki is the protagonist of Tokyo Ghoul, a manga by Sui Ishida serialized from 2011 to 2014, followed by the sequel Tokyo Ghoul:re (2014-2018). He is a college student who becomes a half-ghoul after receiving an organ transplant from a ghoul named Rize Kamishiro. Unable to eat human food and craving human flesh, Kaneki must navigate the conflict between humans and ghouls while struggling to maintain his identity. The manga has sold over 47 million copies.

What Is a Ghoul in Tokyo Ghoul?

Ghouls are humanoid creatures that can only survive by eating human flesh. They appear identical to humans but possess kagune — predatory organs that manifest as tentacle-like appendages used for combat. Ghouls are physically superior to humans and can regenerate from severe injuries. They are hunted by the Commission of Counter Ghoul (CCG), a government organization that uses weapons made from ghoul kagune. Kaneki's transformation into a half-ghoul places him between both worlds.

What Happens During Kaneki's Torture?

Kaneki is captured by Jason (Yakumo Oomori), a ghoul who tortures him by repeatedly severing and regrowing his fingers and toes using pliers, while forcing him to count backward from 1,000 by sevens to maintain consciousness. The torture lasts approximately ten days. Kaneki's hair turns white from stress (a condition called Marie Antoinette syndrome). He emerges psychologically transformed — having accepted his ghoul nature and abandoned his previous pacifism.

What Is a Kakuja?

A kakuja is an advanced ghoul form achieved through repeated cannibalism (eating other ghouls). It manifests as armor-like kagune that covers the body. Kaneki develops a centipede-shaped kakuja — the centipede being the creature his torturer Jason used during his captivity. Early kakuja forms are unstable and can cause the user to lose rational thought. Kaneki's kakuja represents both his trauma and his power.

Is Tokyo Ghoul a Horror Manga?

Tokyo Ghoul is classified as dark fantasy/action but contains significant horror elements, including graphic violence, body horror, psychological torture, and themes of identity loss. The series is primarily a character study about the cost of violence and the question of whether someone can remain themselves after experiencing extreme trauma. It has been compared to Kafka's The Metamorphosis for its exploration of involuntary transformation.
