Ayato is an arrogant, brash teenager, with a similar hot-blooded attitude resembling his sister's, while he normally displays either a scowl or menacing smirk on his face. Other than his physicalities, he shares many similarities with Touka, such as his tendency to use language that is often uncouth or inappropriate. He has a habit for kicking people over the simplest mistakes; such as when Kaneki failed to address him with the desired honorific, or when Banjou did not return his missed calls. However, he seems to be more harsh compared to his sister, but admits himself to be surprisingly "softer" than his Aogiri superiors. He is a firm believer in the notion that "the weak perish and the strong survive," which was triggered by the death of his mother and father. Ayato bears deep grudges against his father, Arata, for abandoning him and Touka when they were young. Ayato has even stated that the whole reason for hating Kaneki was his resemblance to Arata. It was also pointed out by Kaneki that Ayato cares deeply for Touka subconsciously, as shown when he beat her down first rather than allowing her to suffer a slow, torturous death from Yamori. Later on, he also took her alias, "Rabbit" so the CCG would hunt him instead of Touka. Ayato also seems to have a soft spot for rabbits.
