Initially, Pomni has a high-strung, shy, and tense demeanor. In the pilot episode, she is shown to be extremely anxious and troubled regarding her predicament, even succumbing to denial and exhibiting signs of delusion. When she finds the "exit", she experiences moderate signs of paranoia and seems to believe she is hallucinating. She's also on the clumsy side, as she tends to accidentally bump into things and people.
