Paula serves as a deity of the Idaten race, created to protect humanity from demons. As the youngest Idaten at twenty years old, others frequently treat her as the least experienced, explaining world mechanics to her and positioning her as an audience surrogate. She exhibits a rebellious, troublemaking personality, often challenging the status quo and confronting perceived injustices. Despite this, Paula demonstrates fierce loyalty to her fellow Idaten and remains dedicated to their mission of safeguarding humanity.

Physically, Paula features a youthful appearance, long blonde hair typically tied in a ponytail, and black eyes. She wears a distinctive black leather outfit with a red cape. Her combat style emphasizes physical prowess, though she ranks weaker than senior Idaten like Rin or Hayato. She effortlessly intercepts bullets, showcasing supernatural reflexes and durability.

Within the Idaten group, Paula forms one-third of a power trio alongside Ysley (intellect) and Hayato (physical strength). She embodies the "Beauty" aspect due to her girlish charm and appearance, fitting the "Badass Adorable" trope by combining a sweet, lovable demeanor with formidable combat capability.

Her development reflects the Idatens' blue-and-orange morality. Like her kin, she remains indifferent to human suffering unless it threatens humanity's extinction. This detachment is tested during the conflict with the Zoble Empire and its demonic allies. Captured alongside Ysley by demons, they endure repeated torture, including dismemberment, exploiting their regenerative abilities. This experience forces her to confront the consequences of the Idatens' collective hubris and ethical compromises.
