Description
In the comedic alternate universe of Ple Ple Pleiades 2, Cocytos is portrayed as the manager of the 5th Department within the Nazarick Corporation. His role is a stark departure from his usual fearsome and stoic warrior persona, instead placing him in a mundane corporate setting where he struggles with performance and sales targets. This version of Cocytos is defined by his profound sense of responsibility and his anxious, self-deprecating nature. He is not a proud insectoid warrior but a beleaguered middle manager, consumed by the fear of failure and desperate for approval from his superiors.

His primary motivation stems from a deep-seated loyalty to the company and its leader, Ainz Ooal Gown. This loyalty is expressed not through battle, but through his overwhelming shame at having failed in his duties. When confronted with the massive deficit his department has accrued due to a failed business deal, he is immediately overcome with groveling fear. Rather than making excuses, he immediately offers Ainz his letter of resignation, believing he is unworthy of his position and that this is the only honorable way to atone for his mistake. This act reveals a personality that is both honorable and deeply insecure, where his entire sense of self-worth is tied directly to his job performance.

Within the story, Cocytos serves as a source of humor through the exaggerated contrast between his imposing, insect-like design and his pitiful, anxious demeanor. He is a key figure in the episode that focuses on the company's internal struggles, highlighting the absurdity of applying life-or-destiny stakes to corporate profit margins. His role is to demonstrate the immense pressure and fear that the floor guardians feel in this world towards Ainz, who acts as a surprisingly lenient but still intimidating CEO. The narrative uses his failure to showcase Ainz's unexpected management style, where he chooses to forgive the mistake and encourage learning from failure rather than punishing the subordinate.

Key relationships in this universe are defined by corporate hierarchy. His most significant relationship is with Ainz, whom he views with a mixture of utter devotion and paralyzing fear. When Ainz returns his resignation letter and offers words of encouragement, Cocytos is left speechless at this act of leniency, swearing to work even harder in the future. This interaction solidifies his loyalty and deepens his resolve. He also shares a brief, quieter moment with Demiurge, another floor guardian, at an oden stand after the incident. In this setting, he reaffirms his oath to serve Ainz forever, to which Demiurge responds with amused bemusement, highlighting that such a pledge is so obvious it barely needs stating. This simple scene indicates a sense of camaraderie and shared understanding between the two colleagues.

There is little to no character development for Cocytos in the traditional sense, as the series is a short-form parody. However, he does experience a moment of emotional catharsis and renewed purpose. He begins the episode in a state of utter despair, convinced his career is over. After Ainz’s merciful response, he is reinvigorated, transforming from a groveling mess into a loyal subordinate determined to succeed. This shift is not a change in his core personality but a restoration of his confidence, solidifying his role as a devoted, if anxious, servant.

Regarding notable abilities, Cocytos in this setting possesses no combat skills or magical powers. His abilities are strictly corporate and character-based, consisting of managing a sales department, failing at business negotiations, and exhibiting a remarkable talent for abject groveling and self-flagellation over his professional shortcomings. His defining action is the immediate drafting and presentation of his own resignation letter, which serves as his primary method of problem-solving. The humor of the character derives entirely from the absence of his usual combat prowess and the presence of these very ordinary, human failings.
