Her personality goes all over the place. Sometimes, she's a genuinely nice girl; other times, she trollsAbukuma. She often expresses her annoyance with the destroyers. She is likes to boast of her abilities, such as referring herself as "Super Kitakami-sama" after remodeling.
The nature of her relationship with Ooi varies but they are usually very close to each other. In some versions, Kitakami is straight while Ooi is a lesbian, and Kitakami has to repeatedly shred Ooi's delusions. In others, they're a romantic couple. In yet further versions, they're both bisexual and have eyes for the Admiral and each other.
