Masks (マスク, masuku) are worn by ghouls to prevent their identities as 'humans' from being discovered by the CCG. Several masks bear a symbolic attachment or representation to their owner. They heavily influence the alias of some ghouls filed under by the CCG.
|Ken Kaneki/Haise Sasaki||Eyepatch/Centipede|| Kaneki's mask was designed by Uta. It was modeled after Kaneki's situation, becoming an artificial one-eyed ghoul. As Uta explained, only the left eye was exposed was because he wanted to see the world that was hidden beneath the medical eye-patch Kaneki wore, as he was unable to control his kakugan from manifesting at that time. Kaneki's transformation into a one-eyed ghoul reflects on the apparent Frankenstein motif of his mask.
The mask is mainly made out of leather and covers most of Kaneki's face with the exception of his left eye and hair.
The mask has "artificial" teeth and exposed gums on it to make it look more realistic. The mask also has a zipper to increase its efficiency; to prey on meals and consume them while protecting Kaneki's identity without the need to remove it.
|Touka Kirishima||Rabbit||The mask of Touka is a cartoon rabbit covering all her face (except for her hair), which then gives her the alias Rabbit. The rabbit's head is white and it has two long ears with pink highlights.|
|Ayato Kirishima||Rabbit/Black Rabbit||A variation of Touka's, Ayato donned this mask to convince the CCG he was the one responsible for Kureo Mado's death and turn them away from Touka.|
|Renji Yomo||Raven||Yomo's mask is modeled after a raven beak.|
|Enji Koma||Devil Ape||This mask was used by Enji Koma during his days as the leader of the ghoul gang the Devil Apes and later during the Anteiku Raid. Members of the gang also wore these masks.|
|Kaya Irimi||Black Dog||This mask was used by Irimi when she was the leader of the Black Dobers and during the Anteiku Raid. Like the Devil Apes, members of the gang also wore these masks.|
|Kurona Yasuhisa||Kuro||A mask with vertical stripes, the hole on the mask indicates where Kurona's ghoul eye is.|
|Nashiro Yasuhisa||Shiro||Unlike Kurona's, Shirona's mask has horizontal stripes. However, this mask also has one eye hole over her ghoul eye.|
|Kanae von Rosewald||Rose||Kanae wore several masks over the course of the series. The first one was a party mask used by the ghouls during the Auction. The second one was the mask worn by the servants of the Tsukiyama family when they hunt. Her final mask is given to her after her torture at the hands of Eto, and its teeth motif distinctly resembles Noro's.|
|Yakumo Oomori||Jason||Yamori wore a white mask resembling a hockey mask. This is a reference to Jason Voorhees, the antagonist of the Friday the 13th series.|
|Bin Brothers||Tail Brothers|
|Uta||No Face||Uta has worn two distinctly different masks so far. During his early days, he wore a flat mask with stripes running horizontally. During the Auction Raid, Uta wore a beaked mask with several small holes on its side. Despite wearing two different masks, Take Hirako was still able to identify him as No Face.|
|Nimura Furuta||Souta||This mask is used by Furuta to infiltrate the Clowns as Souta.|
|Uruka Minami||Lantern||Minami's mask is a Jack-o-Lantern pumpkin, hence her name. It's one of the few masks known in Tokyo Ghoul to cover the entire head.|
|Low-ranking Aogiri Tree members||Low-ranking Aogiri members wear these identical masks alongside their hooded robes.|
|Tooru Mutsuki||None||This mask was made by Uta to help the Quinx Squad go undercover as ghouls. The mask resembles a mummy and exposes Mutsuki's right eye where his kakugan is.|
|Saiko Yonebayashi||None||This mask was made by Uta to help the Quinx Squad go undercover as ghouls.|
|Ginshi Shirazu||None||This mask was made by Uta to help the Quinx Squad go undercover as ghouls. The mask somewhat resembles a cartoon shark grinning with its teeth visible.|
|Kuki Urie||None||This mask was made by Uta to help the Quinx Squad go undercover as ghouls. This beaked mask covers the upper half of Urie's face and his chin, with an opening where his mouth is.|
