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.

Albedo
Due to Cocytus' simple minded thinking, he sometimes misjudged Ainz' orders and it led him to failing his tasks. Albedo would scold him or glare at him when this happens. Other than that, they are on good terms with each other.

Shalltear Bloodfallen
Cocytus is one of Shalltear's colleagues. Like her, he has experienced the taste of failure, so both share the same feeling of redeeming themselves in front of Ainz.

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
Cocytus respects the Lizardman for his fighting spirit and ingenuity in combat. Cocytus petitioned to Ainz Ooal Gown to resurrect Zaryusu, as he believed it would be a pity to condemn such an admirable warrior to oblivion. He is currently overseeing Zaryusu's training and is always on the lookout to provide better equipment for him and all of the Lizardmen that are under his care.
