"hm...hi. I'm nayuta. It's a pleasure to meet you." Unlike her predecessor Makima, who was a manipulative, irredeemable monster, Nayuta is more akin to a spoiled, yet compassionate girl, thanks to Denji's influence. She is extremely spoiled and controlling viewing Denji as her property, getting angry when he kissed Asa. She was also quite greedy and spoiled demanding daily ice cream in exchange for turning Asa back to normal and even controlled her classmates into giving her their desserts. Despite her willingness to integrate and associate with human society even having friends, she like any other Devil is indifferent towards them. She looks down on humans and is more than willing to kill them if they prove to be a threat to her or Denji claiming that it's natural and a part of her nature comparing it to fish swimming, or plants photosynthesizing. At one point she even contemplated helping her kind destroy humanity in the upcoming Prophecy of Nostradamus citing that human society is restrictive and she wants to be free do do as she pleases, although her attachment to Denji and his disagreement with the extermination of mankind made her acquiesce to preventing it. Perhaps a holdover from her previous incarnation's obsession with turning Denji into her "dog," Nayuta holds a strong affection for real dogs, collecting several, despite the restrictions of sharing space in her and Denji's somewhat small apartment. She enjoys the smell of dogs, claiming that wet dog smell is pleasant, and it reinforces the comfort she felt around canines; similar to Makima, she sometimes equates Denji to a dog, but in an affectionate way, rather than a dehumanising manner like her predecessor. Despite her flaws she is genuinely a good person at heart. She deeply cares for Denji and is extremely protective of him being willing to risk her life to save his and even considering him as family.
