Overview

Tokyo Ghoul √A Episode 4, titled “Deep Layers” (Shinkō), shifts the focus toward the growing tension between Aogiri Tree, Anteiku, and the CCG. As Ken Kaneki continues searching for answers about Dr. Kanou and the experiments that transformed him into a half-ghoul, new alliances and hidden agendas begin to emerge. The episode balances investigation, character development, and world-building while preparing viewers for the larger conflicts that define the second half of Tokyo Ghoul √A.

Episode Summary

Following the destruction of the Ghoul Restaurant, Ken Kaneki resumes his search for the truth behind his transformation. Believing that Dr. Akihiro Kanou holds the answers, Kaneki continues working with Aogiri Tree while secretly pursuing his own investigation. Although he cooperates with the organization during missions, it becomes increasingly clear that his loyalty lies only with his personal goal rather than Aogiri’s ambitions.

Elsewhere, the Commission of Counter Ghoul (CCG) reviews the results of its recent operation and begins gathering intelligence on both Aogiri Tree and Dr. Kanou. Koutarou Amon and Akira Mado continue investigating unusual ghoul-related incidents, suspecting that someone is creating artificial half-ghouls through illegal experiments.

At Anteiku, Touka Kirishima struggles to accept Kaneki’s absence. Yoshimura encourages her to respect Kaneki’s decision, even though everyone at the café worries that he is isolating himself from those who care about him. Nishiki Nishio and the other Anteiku members remain concerned about the dangerous path Kaneki has chosen.

Meanwhile, Aogiri Tree prepares for its next operation. Kaneki’s growing strength earns the attention of several high-ranking members, while mysterious figures connected to Dr. Kanou begin moving behind the scenes. The episode hints that Kaneki’s transformation is only one part of a much larger conspiracy involving both humans and ghouls.

The episode ends with Kaneki drawing closer to the truth, while the CCG and Aogiri unknowingly move toward another inevitable confrontation.
