''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.
