ابیسس

One of the people with "light" who are constantly launching assaults on those without "light" in Anti-Zegapain ships in order to destroy servers. Referred to as the Demon Soldier of the Gards-orm, he is almost incomprehensible to the Celebrants. He and Sin can revive themselves numerous times because once their bodies are destroyed, they can simply transfer their data and awaken in a new body.

[Spoiler: He and Sin meet their end when Chris destroys all their replacement bodies and the two Gards-orm die in battle.]
