Cocytus/Relationships

Ainz Ooal Gown
Cocytus considers himself the 'sword' of Ainz Ooal Gown, an object that does as he is told without ever questioning his master. 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'. Also, when Ainz sent a Death Knight to ask the guardians what they wanted Cocytus asked that Ainz produce an heir and hoped to teach the "young master" swordsmanship, but due to Ainz being a magic caster he thought that the heir will an outstanding magic caster so he settled for protecting the "young master" and even daydreamed about it. Cocytus also greatly feared that Ainz would abandon them due to him disappointing him with his failure in conquering the Lizardmen and was greatly relieved after leaning that Ainz did not blame nor was he angry at him.

Warrior Takemikazuchi
Warrior Takemikazuchi is Cocytus's creator and previous wielder of the God Slaying Emperor Blade. Cocytus holds this blade to be one of his prized possessions so as to keep the memory of his creator close. Cocytus also shares his creator's knack in creating suitable names.

Albedo
Due to Cocytus' simple minded thinking, he sometimes misjudged Ainz's 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 urge 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 9th Floor of Nazarick. He respects Demiurge's intelligence and confides in him on deciphering Ainz's plans.

Aura Bella Fiora
Aura is Cocytus's colleague. Cocytus doesn't like it when Aura says that he's nude because it makes him sound like a pervert.

Victim
Victim is Cocytus's colleague. They do not see each other often. Despite this, they maintain a cordial and respectful relationship.

Kyouhukou
Cocytus is on good terms with Kyouhukou.

Gashokukochuuou
Cocytus is on good terms with Gashokukochuuou.

Sebas Tian
Sebas is Cocytus's colleague and one other of the few good aligment NPC of Nazarick. Althought he was ready to fight and kill Sebas if he were to be revealed as a traitor, he doesn't show any ill intention against the butler after his innocence was determinated. It's unknown if the two of them share the friendship and rivality of their creators.

Narberal Gamma
Cocytus and Narberal are close to each other and get along unexpectedly well due to their creators being close friends.

Entoma Vasilissa Zeta
Entoma was sent by Ainz to accompany and observe Cocytus in the war against the lizardmen. Cocytus tried to read her expression, but gave up since her face is just a mask used to hide her true identity. He even remembered the words of his friend, Kyouhukou, that Entoma is the scariest one of the Familiar Eaters.

Iguva=41
For a short time, Iguva=41 was Cocytus's subordinate. Despite being under him, Cocytus felt guilty of losing him in battle to the lizardmen, since heZaryusu Shasha

Cocytus respects Zaryusu for his fighting spirit and ingenuity in combat. Cocytus petitioned 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.

Zenberu Gugu
After the conquest of the Great Lake, Zenberu became Cocytus' subordinate. They have a good relationship though Cocytus is dismayed at the lack of proper manners Zenberu displays when talking to his master, Ainz Ooal Gown. He would have killed him on the spot for his insolence had it not been for Ainz's intervention.

Sous-chef
Cocytus is one of Sous-chef's regulars at the bar.
