This cube craft paper toy is the Nurarihyon, based on the manga series Nurarihyon no Mago (also known as Nura: Rise of the Yokai Clan). This papercraft is designed by blackignus. Nurarihyon is Rihan's father and Rikuo's grandfather. He was the founder and first Supreme Commander of the Nura Clan.
As a Nurarihyon, his head protrudes backwards from his face in the shape of a gourd. Nurarihyon wears a brown robe over a dark green kimono with traditional Japanese sandals.
In the past, Nurarihyon was significantly taller. His hair was very similar to that of Rihan and Rikuo's yōkai form in that it was long and protruded outward from the back of his head. The top half of his hair was a goldish-white while the bottom half of his hair was black. Nurarihyon's outfit consisted of a red cloak over a black kimono and zōri, along with a three-eyed, three-tailed wolf hanging around his shoulders like a shawl. Black ink-like markings could be seen around his eyes and in his hair.
400 years ago, in his prime, he seemed overeager and a bit rash in his quest to become the Lord of Pandemonium. He was also hot-headed, as seen when he attacked Nijō Castle without any planning and even without definitive knowledge that his Hyakki Yakō would come to assist him, all to rescue Yōhime.
Though it's said that he plays pranks on humans, he doesn't really hate them - rather, he doesn't believe humans should interfere in yōkai affairs. He dislikes the fact that Rikuo goes to school and acts human but he respects his wishes.
In the present, he is a bit more perverted than 400 years ago. He has also become calmer and thinks his decisions through. He tends to have a habit of investigating things on his own without informing others, even disappearing for long spans of time without prior notice. Once Rikuo decided to accept the mantle of leading the Nura Clan, Nurarihyon proved to be very demanding of his grandson - primarily because he believed that Rikuo was capable of surpassing even himself.
