Appearance
Due to having yōkai blood in his lineage, Rikuo has two forms: one in which he takes a human form, and another where his yōkai blood takes over and he becomes a full youkai. The former is frequently called his "Day" form, whereas the latter is called his "Night" form, as originally he was only able to maintain it during darkness.Human form
Within the Nura House only, he can also be seen wearing a replication of Nurarihyon's past outfit: a cloak over a black kimono with traditional Japanese sandals (zōri), only Rikuo's cloak is blue instead of red.
Yōkai form
His appearance resembles that of Nurarihyon and Rihan in that his hair is long and protrudes out the back of his head. Like Nurarihyon, the top half of his hair is white while the bottom half of his hair is black. Always, his yōkai form is seen with a blue cloak over a black kimono zōri.
Midway through transforming into his yōkai form, Rikuo temporarily retains his human form's outfit. His hair grows longer and turns black and white, although not as long as his fully transformed form. He also appears taller than his human form, but still shorter than his full yōkai form.
Personality
His Day Form (Human) is seemingly weak but very clever, easily manipulating one of the council members into isolating himself during a meeting and rationalizing against the dissolution of the Gyūki Group. Originally he couldn't remember things he did as his "Night" form, but he later is able to remember and he decides to form a own "Hyakki Yakō" .Yōkai form
His Night Form (yōkai) is confident, strong and inspires "Fear" amongst his allies, leading many to join him. He handle the human side of things with his "Day" form and handle the yōkai-side with his youkai form. While normally calm, reserved and in control, Rikuo can exhibit merciless conviction when in the presence of anyone whose beliefs challenge his, making him very dangerous once provoked. After losing a fight to his grandfather, he is taken to the yōukai village of Toono to train and finally learns what type of demon he is, thus gaining stronger abilities. He has departed for Kyoto to face Hagoromo Gitsune, save Yura and avenge his father. He seems to get stronger when his "Day" and "Night" blood mix.
History
Growing up, Rikuo was surrounded by a wide variety of yōkai - many of whom watched after him at his grandfather's behest. He frequently pulled pranks on them, and viewed his grandfather and the yōkai world with a sense of awe. When he was 8, his father was stabbed to death in front of him. As a child, he was excited at the prospect of succeeding his grandfather and becoming the Nura Clan's Third Head. However, thanks to Kiyotsugu's school presentation, Rikuo learned that yōkai were actually renowned for doing evil deeds. When he tried to contest it with knowledge of the yōkai in his household, his classmates teased and ostracized him. As a result, he decided it was best not to mention yōkai around other humans.
At a routine Nura Clan council meeting, Nurarihyon formally announced his intention to pass leadership of the clan to Rikuo. However, due to his new-found knowledge of yōkai nature, Rikuo adamantly refused the position. A clan board member, Gagoze, who had believed himself best suited to the position, attacked a school bus he believed Rikuo to be riding in an attempt to kill the boy. Once Rikuo learned that his friend Kana was in danger, he tried to mobilize the Nura Clan Hyakki Yakō to save those who had been riding the bus. When Mokugyo Daruma stopped him, stating that a human couldn't command the Hyakki Yakō, Rikuo awoke to his yōkai blood for the first time and replied that it would be fine if he were a yōkai himself. At the site of the accident, he faced and defeated Gagoze and declared his intent to become the lord of all yōkai. Shortly afterward, he reverted back to his human form and fainted - forgetting the incident entirely.
Since then, he has attempted to become more like a normal human by doing all sorts of good deeds, though he still trusts and is friendly with his yōkai underlings.
