Ayato Kirishima

Ayato Kirishima (霧嶋 絢都, Kirishima Ayato) is Touka Kirishima's younger brother. He grew up with his sister in the 20th ward but at some point of time, he disappeared. Currently, he is an executive of Aogiri Tree.

Personality
An arrogant youth with a similar harsh attitude resembling his sister. Other than physical looks, he shares many similarities with Touka such as his cold, hotblooded attitude and a habit for kicking people. However, he's more harsh compared to her and surprisingly nicer than his Aogiri superiors. Ayato holds great hatred towards his father Arata for abandoning him and Touka when they were young. Ayato even stated that the whole reason why he hated Kaneki was his resemblance to Arata. It is also pointed out by Kaneki that Ayato cares deeply for Touka subconsciously when he beat her down first rather than suffer a slow, torturous death from Yamori.

Aogiri Arc
Ayato ordered Kazuichi Banjou to search for Rize Kamishiro. When Banjou didn't answer his phone calls, Ayato feared that Yamori and Nico would overtake him. Thus, he decided to go himself to Anteiku, where the 20th ward's information is collected. Together with Yamori and Nico, he fought Touka Kirishima and Ken Kaneki at Anteiku. He defeated Touka in this fight and took Kaneki to the Aogiri hideout together with Yamori and Nico.

In the hideout, Ayato brought Kaneki to Tatara. On the way, Kaneki asked Ayato about Touka's state, but Ayato hit him as an answer and told him that he was not allowed to ask and follow orders obediently. After Tatara had decided that Kaneki could not be used, Tatara allowed Ayato to do with Kaneki as he liked.

Power and Abilities
A lifetime of fighting against CCG investigators and ghouls has resulted in Ayato being well versed in hand to hand combat with the ability to overcome experienced opponents such as his sister Touka. Combining his kagune's advantage in long distance attacks with his close combat capabilities makes Ayato a strong opponent to defeat.
 * Ukaku Kagune: Like his sister, Ayato is able to release RC gas and can form a single wing on both of his shoulders. Like many Ukaku ghouls, he is agile and able to shoot bullets from both wings. However he also suffers from a low RC supply and therefore tires if a battle is dragged out for too long.
