A uniquely-shaped huge Aragami with innumerable tentacles and eyes. Also known as the Conqueror of the Plains, its body is the size of a mountain. As well as its tentacle attacks, it emits a large-caliber beam. Origins unknown.
Avoid medium-to-long range combat. Stay out of its reach and repulse it with gunfire, then strike with one's sword to be safe. When activated by rage, its legs become vulnerable.
Its name is inspired by "Ouroboros", symbol of Immortality.
