|Occupation||Servant of Akura-Ou|
Yatori (夜烏) is the loyal servant of Akura-Ou (now Kirihito) and previously worked for him. During that time, he was known as 'furball'.
Yatori was previously known as 'furball' and worked for Akura-ou after the said man killed his original master in a game of siege. He was constantly ignored and ridiculed for his looks and stench. His tolerance for it soon reached it's peak when he was partnered with Kirakaburi.
When his accomplice became gravely injured by Tomoe's sword, he gorged on him. Due to this, his size and strength grew considerably. He soon finds out a human, namely Suke, was watching him and makes him beg for his life. He relished this feeling of superiority.
Afterward, he aimed to get Akura-ou's recognition and protected him from human intruders by eating them. However, he was rejected again due to his appearances. Desperate to please him, he goes to Suke and makes him eat him. He gains control over the body and afterward assumed the name 'Yatori'.
In the past when he was known as 'Furball', he was, as his name implied, resembles the shape of a ball and was covered in fur except where his face was. He had large almond-shaped eyes with spirally pupils and a small nose in between. His only garment was the tall hat on his head.
After consuming Suke's body, Yatori now wears a big lion's-mane like headdress with a red monster's face in the middle. He has slanted eyes with a the same spirally ripple-like pattern. He wears a cheetah-skin patterned kimono with two bear-like paws on either his shoulder.
Already as Yatori, he served falsely under Jirou, manipulating him as to gain control of the Kurama Mountain to prove his worth the Akura-Ou. He kept Third Chief Soujoubou's soul within the Raijiuyuu so Jirou would have the power to rule. However, his plan failed and he returned to Kirihito.
He accompanied Akura-Ou on his second trip to Yomi-no-Kuni, where they discovered Akura-Ou's body atop a mountain of flames, upon realising they could not climb it he pursuaded a reluctant Akura-Ou to return to the surface until they could formulate a successful plan.
Yatori admires Akura-Ou. He has very high regards and is very loyal to him. He states that the world under Master Akura-oh is his ideal world and his wish is to become Akura-ou's number one, a wish that is declined much to his dismay. Despite Akura-ou's attempt to kill him by taking him to the Yomi-no-kun under the assumption that Yatori would turn to dust Yatori claims that the only thing he couldn't forgive Akura-ou for would be if he changed.
Akura-ou does not recognise Yatori as his past self largely due to his new appearance. Yatori does not reveal his past identity or the fact that he is aware that Kirhito is actually Akura-ou in human form until later in the series when his other option was to lose a hand.
Yatori first met Nanami on Kurama mountain where she defeated him with a barrier against evil, despite this he survived and has wanted to kill her since. He becomes concerned throughout the series of Nanami's influence on Akura-ou and begins to fear she may change him. In Chapter 120 he suggests they kidnap Nanami to have Tomoe put out the hellfire engulfing his body, Akura-ou angrily refuses ordering him not to lay a hand on her. Yatori then asks if Akura-ou has feelings for Nanami, a question which Akura-ou dodges saying Yatori speaks too annoyingly.
Yatori detests Kikuichi seeing him as competition for Akura-ou's approval. He frequently calls him names such as trash and unreliable. He is jealous of the more positive relationship Akura-ou has with Kikuichi and is always trying to one up him.
