Diyuma

Diyuma is a monstrous beast mostly known to the eastern continent of the Naruto World. It cannot be completely perceived as a 'Tailed Beast', but it does have many tails - total eight of them. However, its tails have other meaning. They don't work as its main feature. Diyuma's main characteristics are its eight feet and Black Eyes - the pitch black eyes with white eyeballs, giving it a monstrous look.

Diyuma is shown in FanFic book The Legend of Diyuma (Gaara's Romance #1) by Tamuna Tsertsvadze.

Diyuma is said to be the essential part of Sacred Spirit - the deity of souls, which dwells in the centre of the universe and grants people their souls, giving them the soul energy. This spirit which shows itself to humans in form of a yellow energy Hell Horse, is merged within the body of human clan, the Shin-Lin clan. But actually this relationship of humans with Diyuma has an interesting history.

The eastern legend tells us that the soul energy manipulating power was forbidden for humans to discover and use, however, one powerful ninja clan which was formed after Hagoromo Otsutsuki's spread of Ninshu and then Ninjutsu knowledge, discovered this power due to their talent and skills, and used it for their purposes - they started wars, and regarded everyone other as inferior, considering themselves gods, as the power of soul energy granted them huge strength no human had ever seen before. But due to their evil purposes and deeds, their soul energy grew dark, and started consuming them. The ones who could control at least a tiny bit of their black powers, survived, and the others got consumed and died. But after gaining control over these black powers, the blackened ninja became invincible, and dark-hearted as well, for their soul was completely blackened... And so, their clan was named 'Hei' ('Black' in Mandarin Chinese).

To oppose this evil clan, the forest dwellers, Lin clan, which had good relationship with spirits, asked the Sacred Spirit for its help, begging it to aid them, and they would be true to it for eternity.

Sacred Spirit accepted this proposal, and sent its central part, Diyuma Hell Horse, to the earth, where it merged with the Lin clan's Elder, the powerful kunoichi, Hao Lin. The power was so overwhelming that it was extremely hard to control, but Hao, with her kind heart and purity, managed to tame it. However, the spirit which dwelt into her body, consumed her own soul, turning her monstrous - she would feel no taste of any food or water, and was doomed to drink blood for the rest of her life. But the Lin clan regarded her as a deity nevertheless - because the kind woman became even more powerful than before, obtaining enormous strength no human had ever seen, and with this power, the Lin clan, later merging with Shin clan and turning into combined Shin-Lin clan, eventually managed to defeat Hei.
