Pomni has a high-strung, timid, and paranoid demeanor. In the pilot episode, she is shown to be anxious and troubled in regards to her predicament, even succumbing to denial and exhibiting signs of paranoia and delusion. When she finds the "exit", she experiences moderate signs of paranoia and seems to believe she is hallucinating. Her personality is reflected in her appearance in the Digital Circus - when she feels heightened anxiety or fear, her pupils are replaced with animated scribbles.

In her initial appearance, Pomni is shown to have a degree of both empathy and selfishness, as she went back to check on Ragatha after the latter was attacked by an abstracted Kaufmo, and promised Ragatha that she'd find Caine to fix her. However, Pomni's desire to escape the digital circus overrode this, as she entered the exit door upon finding it and left Ragatha behind without hesitating. She later felt remorse for this action once Ragatha was fixed by Caine.
