Cocytus/Relationships

Ainz Ooal Gown
When Demiurge brought up that they could serve Ainz's possible future heir, he got interested and hoped that he gets to be called 'uncle'. He self-describes himself as the 'sword' of Ainz Ooal Gown, an object that does as he is told without ever questioning his master.

Warrior Takemikazuchi
Warrior Takemikazuchi is Cocytus's creator and previous wielder of the God Slaying Emperor Blade. Cocytus holds this blade one of his prized possessions so as to keep the memory of his creator close.

Shalltear Bloodfallen
Cocytus is one of Shalltear's colleagues. She and Cocytus share the same feeling of redeeming themselves in front of Ainz after their failure.

Demiurge
As a fellow Floor Guardian, Demiurge is a colleague and at the same time a rival. Despite their rivalry for Ainz's attention and praise, they have a stable work-relationship. They are civil to one another to be considered drinking partners at Sous-chef's bar on the ninth floor of Nazarick. He respects Demiurge's intelligence and confides in him on deciphering Ainz's plans.

Zaryusu Shasha
He respects the Lizardman for his fighting spirit and ingenuity in combat.
