Vasuki

Vasuki is a recurring demon in the series.

History
Vāsuki is a serpent king in Hindu mythology who is described as having a gem called Nagamani on his head. Vāsuki is famous for coiling around Shiva's neck, who blessed and wore him as an ornament.

In the legend of the churning of the milk ocean, Vāsuki allowed the Devas and Asuras to bind him to Mount Mandar to use him to churn the Amrita, the nectar of immortality. This happens after the devas and the asuras agree to join forces in order to gain the Amrita. It is also said that Indra tricked the asuras into holding Vāsuki by its heads, so that they could inhale its hot breath. However, as the milk ocean was churned up, a poison seeped out which threatened the world. So Shiva swallowed the venom as an act of self-sacrifice to prevent premature destruction of the world, thus earning him the title of Nilakantha ("blue throat"). He has a sister called Manasa, who is a goddess of snakes and poison.

Vasuki is also recorded in Buddhist mythology, as well as the mythology of China and Japan, as one of the "Eight Great Naga Kings" (known in Japan as the Hachidai Ryuu-Ou). In Buddhist mythology, he, along with the other naga kings, appear in the audience of many of the Buddha's sermons.
