"Fifth Floor Guardian Cocytus, at your command."
— Cocytus' Introduction

Cocytus (コキュートス) is a Floor Guardian of the 5th Floor in the Great Tomb of Nazarick. He is the creation of Warrior Takemikazuchi.

Appearance

Having an enormous body size of 2.5m, Cocytus has the appearance of an insect walking on two feet - a fusion between a mantis and an ant. With a tail twice as long as his height, Cocytus is covered in sharp spikes like icicles and has a strong jaw that can easily snap people's hands.

Two of his hands hold a silver halberd, while the remaining two hands hold a mace emitting black light and a crooked shape sheath which seems to be for a broadsword. With a breathtaking cold air, the pale blue, hardened bone armor oozes out diamond dust like bright light. His shoulders and back look like uplifted icebergs.

Personality

Cocytus has a warrior personality, respecting anyone with a fighting spirit, and the heart of a warrior. As a Floor Guardian, he is in charge of Nazarick's martial defense. Cocytus is loyal to a fault. As shown when he prevented Demiurge, under Ainz's order, from interfering in Ainz's fight against Shalltear even though he too also feared the possibility of losing his master.

As Cocytus is a warrior by heart, he likes a good battle and has a sense of honor. Unlike his isolationist and xenophobic colleagues, he is more accepting of allowing outsiders to join Nazarick.

Though Cocytus takes pride in his position as Nazarick's defender, he is somewhat envious of his fellow Floor Guardians. Cocytus likens himself as the 'sword' of Ainz Ooal Gown, that executes his master's wishes. He thinks the only way he could prove his worth to Ainz is by actually defeating the invading forces that would pose a threat to Nazarick. Cocytus is not fond of asking for assistance in order to save face, but when the need arises, he will put his pride aside to accomplish his task.

Background

Cocytus was created by Warrior Takemikazuchi as the Floor Guardian of the 5th Floor of the Great Tomb of Nazarick. He was programmed to possess knowledge on all of the Supreme Beings' Divine Weapons.

After the undead relayed questions on who Cocytus is the friendliest within Nazarick, he expresses that it would be Demiurge, Kyouhukou, Grant, and Gashokukochuuou. As for his desires, it would be to spar with Sebas Tian, Albedo and even Ainz if permitted. Another wish that wants is for Ainz to have an heir so that the future of the Guardians will be secure and the chance to train said heir.[2]

Main article: The Show Must Go On! Arc

Cocytus was among the judges of the auditions in selecting the person for Juliet. He was in disbelief that Demiurge supported the idea for a competition between the two Floor Guardians, Albedo and Shalltear. Later on, he was training on the 5th Floor and was approached by Shalltear. Cocytus knowing something suspicious was up, attempted to rebuff her. His suspicion was true when she tried to bribe him to vote for her in the auditions. However, when she offered the role of Tybalt to him, for a chance to exchange blades with Ainz, he was tempted by the idea. Cocytus, though being an honorable warrior, refused and told her to leave. During the audition, Cocytus was moved by Albedo's performance which resulted in him voting for her.[5]

Main article: The Lizard Man Heroes Arc

Cocytus was ordered to annihilate the lizardmen and commanded the undead army of Nazarick. Seeing his army being defeated by the lizardmen, Cocytus requests advice from Demiurge, who he considers to be his rival and does not want to ask for help, but has no other choice. He deploys Iguva=41 to the battlefield. Seeing Iguva=41 being destroyed and his army is being defeated by the lizardmen, he realizes that his mission to annihilate the lizardmen has failed. Cocytus is surprised at his defeat and feels ashamed for losing. This left him no other choice, but to return to Nazarick with a sense of defeat. Still, he is deeply impressed by the lizardmen's victory over him.[7] After his failure, Cocytus asks Ainz if they could spare the lizardmen and make them a part of Nazarick which Ainz agreed.[8]

To redeem his failure, Cocytus was ordered by Ainz to do battle alone against the lizardman heroes lead by Shasuryu Shasha, Zaryusu Shasha, and Zenberu Gugu. After a quick battle, Cocytus kills all of them by his hands. Because Cocytus emerges victorious from his battle against the lizardman, he is now in charge of the occupation of the lizardman tribes.[9]

Main article: The Dark Hero's Story Arc

During the Floor Guardians' meeting on figuring out what to ask Ainz as compensation, clothing was brought up. Cocytus said clothes were unnecessary for him, earning him a tease from Aura that he was naked. He later suggests asking Ainz for weapons as he was interested in adding to his collection and also to provide new equipment for the lizardmen under his charge. When Aura wanted to have Rororo, Cocytus furiously denied it, stating he would not allow his charges' property be taken and would even bring the issue before Ainz's attention should Aura escalate it. He, however, considered Aura's request for keeping the hydra's children.[11]

Main article: The Men in the Kingdom Arc

Ainz Raises Money Arc

Main article: Ainz Raises Money Arc

Cocytus is present with his fellow Floor Guardians at a meeting with their master Ainz Ooal Gown. During the meeting, it’s revealed he requested a voucher to fight with Ainz as his reward. In addition, he formally requested as the Overseer of the lizardman to prevent the seizure of Rororo, by Aura which Ainz deemed reasonable.

Like the others, he was given three gold coins to be used as his salary by Ainz. In the next meeting, he presents his liege how he made the lizardman convert the gold coins into tribal jewelry.

Ainz disappointed that his subordinates refuse to part with the money he gave them orders them to spend. Finding little interest in the goods offered in E-Rantel, the Floor Guardians sought advice from Sebas Tian and Narberal Gamma. Noticing the fan goods of Blue Rose, it prompted the Guardians to use the gold to create their own brand of fan goods based on Momon the Dark Hero.

Later, he would present a "You Can Be Momon Too" Kit to show to his master after purchasing it.[13]

The Craftsman of Dwarf Arc

Main article: The Craftsman of Dwarf Arc

Cocytus greets Ainz when he came to the Great Lake to talk with Zenberu on the Dwarf Kingdom. He was clearly outraged when the lizardman was hesitant to answer Ainz's questions but was held back at the order of his liege. After misunderstandings were cleared up, Ainz informed him of his intentions to go to the Dwarf Kingdom and forge diplomatic relations. Also, Cocytus was willing to offer himself up to his master, so Ainz can sit on his back as a seat, mimicking Shalltear's situation months ago. In a way, his action impressed the lizardmen of Ainz's power over him.[15]

Before setting out, Cocytus was wary of the potential dangers and wanted to personally escort the Sorcerer King during his journey to the Dwarf Kingdom. However, Ainz convinced him that should Cocytus be in peril or negotiations would deteriorate, he would be the first one to be summoned to his side.

Nazarick Mythology Arc

Main article: Nazarick Mythology Arc

Cocytus attended a meeting to create a mythology of his master in order to solidify his hold over the masses. In his myth story, he uses the tone of a classic Japanese children folk tale. Taking place in a small town a boy witnesses the destruction of all he holds dear at the hands of monsters. The boy defeats the monsters using a mysterious power becoming a hero to the people. A sorcerer named Ainz Ooal Gown appears before the boy, claiming to be his father and was using him to lead the foolish humans in order to stabilize the peace. Seeing his work complete he disappears but promises to return to guide the humans once again. The Guardians then comment that Cocytus's story will be popular among children and adventurers.[16]
