Ryraryus Spenia Ai Indarun

Ryraryus Spenia Ai Indarun (リュラリュース・スペニア・アイ・インダルン) is a naga who rules western Tob Forest.

Appearance
Ryraryus is a naga with the upper body of an old man.

Personality
Unlike Goo, Ryraryus's nature is quite discreet. He anticipated the huge power of the Ruler of the Building of Ruin and decided to ally with Goo to attack the Building of Ruin.

Background
For a substantial long time he ruled the western Tob forest and was part of the status qua that kept all monster activity within it in check for countless years.

The Two Leaders Arc
Ainz Ooal Gown appears before the two leaders of the forest. Though Goo arrogantly shows himself before the Overlord, Ryraryus takes caution and uses his magic to turn invisible.

After negotiations had failed, he witnesses Ainz's power as he annihilates Goo and his followers. At first believing he is safe from harm, he tries to use his invincibility ability to hide himself but soon finds out that is untrue as his weak cloaking magic was seen through by Ainz and Aura. Captured and restrained by Aura, she prepares to kill him, but is stopped by Ainz.

Ryrayus pleads for his life, offering to be his servant. His pleads for mercy were accepted and the naga is given control over Goo's territory.

Abilities and Powers
Owning similar strength to Hamsuke, it seems that Ryraryus is also around level 30. Though his physical ability seems to be inferior to Goo, he can use some magic including invisibility. He can also sense the general emotions of a target. It is not clear whether this ability is a Special Talent of him or the racial trait of the Naga.

Goo
Goo was Ryraryus's rival, however the naga agreed to join forces with the troll so as to stand against Nazarick.

Trivia

 * If it wasn't for Ryraryus's meddling, Goo claimed that he would have invaded the ruins in the forest long ago.
