Ukaku

Lore & Background

Historically, the most prominent manifestation of this power belonged to Rize Kamishiro, whose tragic fate inadvertently shaped the destiny of Kaneki Ken. Following her death and subsequent dissection by the CCG, fragments of her DNA were used in various experiments, including the creation of artificial ghouls and the partial transfer of her abilities to others. However, ukaku is far from extinct—many natural ukaku users exist, such as Touka Kirishima and Ayato Kirishima. The CCG had a general interest in Rize due to her high kill count, but no specific priority for her capture above all other targets in her district is established in canon.

Reader's Guide

The Ukaku manifests as multiple kagune tendrils sprouting from the user's back, resembling feathers or fins rather than solid claws. These structures can be detached and manipulated individually, allowing the user to fire a barrage of high-velocity projectiles that curve mid-air to strike targets from any angle. Visually, the wings appear semi-translucent with a fibrous texture, glowing faintly when active. In combat, this power excels at crowd control and maintaining distance, as the user can strafe rapidly while launching continuous volleys of attacks.

The detached pieces can also be used defensively to block incoming blows. Notable users include Rize Kamishiro, who demonstrated the full potential of this ability with terrifying efficiency. Kaneki Ken temporarily utilized a portion of her power after consuming her, giving him access to these winged appendages during critical moments in his early development.

Did You Know?

• The ability to fire projectiles at high speed makes ukaku users formidable at range, but their speed comes at the cost of high RC cell consumption.
• Rize Kamishiro's ukaku was powerful, but the CCG's interest in her was due to her high kill count, not a stated priority above all other targets in her district.
