Tokyo Ghoul

Ken Kaneki is a young man who befriends the enigmatic Rize Kamishiro, unaware that she is a ghoul. Rize reveals her intentions to eat Kaneki but by a stroke of luck Kaneki survives her attack. He is saved by an operation, performed by Dr. Akihiro Kanou, transferring Rize's organs. This subsequently turns him into a half-ghoul half-human hybrid and Kaneki struggles to survive and cope by himself.

Kaneki struggles to adapt to his new nature with no success, until another ghoul, Nishiki Nishio, attempts to prey on his friend, Hideyoshi Nagachika, and he must fight to protect him.

After saving his friend, Kaneki is taken in by Yoshimura, a ghoul who runs the Cafe "Anteiku", who teaches him to blend in human society while hiding his true nature. However, he gets bullied by another ghoul named Touka.

A ghoul named Tsukiyama approaches Kaneki with unknown intentions and the two start hanging out. However, Tsukiyama has prepared a mortal trap where Kaneki is to be killed and eaten. Kaneki finds himself in an arena facing a giant ghoul executioner, Taro, but Tsukiyama intervenes and kills Taro as he wants Kaneki for himself.

Intending to consume Kaneki himself, Tsukiyama prepares another trap, using Nishio's human girlfriend Nishino Kimi as a hostage. Kaneki confronts Tsukiyama and is assisted by Nishio and then Touka. They are no match for Tsukiyama as their kagune are not as strong because they do not consume human flesh, so Touka bites Kaneki, restoring her kagune.

Tsukiyama is defeated by Touka with Nishio's help. Meanwhile, recent developments in the 20th ward draw the attention of the Commission of Counter Ghoul , who sends two of their investigators, Kureo Mado & Kōtarō Amon to hunt down all ghouls in the area. They find Hinami's father and kill him. They then use some of Fueguchi's blood to attract ghouls and trap Hinami and her mother, Ryouko.

Hinami's mother Ryouka is killed by Mado. An angry and vengeful Touka attacks members of the CCG. She kills Kusaba and attacks Amon, but Mado intervenes, using his kagune-like quinque and wounds Touka. Kaneki tells Touka that he wants to fight the ghoul investigators, much to Touka's chagrin, and is given his mask by Uta.

Mado lures Hinami into a trap, but she is followed by Kaneki and Touka.

Amon recalls his early days in the CCG when he was partnered with the experienced Mado. Meanwhile, Touka looks after Hinami above the cafe. Still mourning the loss of his partner, Amon is relocated to the 11th ward, where the CCG have trouble facing dangerous ghouls who do not fear them.

In the 11th ward, Aogiri Tree ghouls attack a CCG branch and kill all the investigators, to the concern of Yoshimura and Yomo. Banjou Kazuichi comes to the cafe looking for Rize, then Touka's brother Ayato arrives. Then Yamori brutally beats and kidnaps Kaneki. The CCG plan an attack on the Aogiri Tree, Touka, Nishio and Hinami prepare to rescue Kaneki with the aid of an unlikely ally: Tsukiyama.

As Kaneki is tortured mercilessly by Yamori, the CCG storm the Aogiri Tree hideout. Meanwhile the Anteiku group infiltrate the building to rescue Kaneki. The CCG gain the upper hand, but are then confronted by the One-Eyed Owl, the leader of Aogiri Tree.

During the physical and mental tortures he suffers at the hands of Jason, who reveals to him that Dr. Kanou turned him into a ghoul on purpose, Kaneki's hair turns white and he sees a vision of Rize. After a lengthy dialogue and analysation of his past with her, comes to accept his ghoul-half and breaks free of his chains. Kaneki fights back, mortally wounding Yamori before devouring his kagune.
