Nayuta

"I've got this... sorta-friend, sorta-little-sister livin' with me. She's smart enough to go to college. I'm saving up for her tuition. See, my life was always crappy before. I want her to have a normal life."

- Denji talking about Nayuta

"[The Control Devil] could only form relationships through the power of fear. So she always longed for something like a family. That's the kind of world she wanted to create. So you create that world for her, okay? Give her lots of hugs."

- Pochita telling Denji the Control Devil's dream

Nayuta (ナユタ) is the reincarnation of the Control Devil (の) following Makima's death.

To prevent her from becoming similar to her previous incarnation, she was taken by Kishibe to be raised by Denji as Denji's younger sister.

Appearance
Nayuta takes the appearance of a young girl with dark brown hair in the colored manga, shoulder-cut hair and with a single large bang that hangs in front of her face, as well as a mole under her left eye. Similar to Makima and Yoru, her eyes are yellow with multiple red colored rings within them.

In the Academy Saga, she has grown visibly taller, appearing to have aged faster than a human would. She has also adopted more of Makima’s visual traits; her shirt is tucked into her pants similarly to how Makima tucked her work shirt in, and her hair is tied up into a braid, albeit flung over her shoulder. In addition, she retains the long bang from her childhood, which has grown to the point that it completely covers her left eye.

Personality
Not much is known about her personality, aside from Denji describing her as a huge-problem child with an extreme personality. As a humanoid devil she has a natural inclination to humans. She seems to like dogs, just like her previous incarnation, as seen by her getting along with Makima's dogs. She is taciturn and very blunt when she speaks.

Like her last incarnation, Nayuta wants an equal relationship and a family, not just relationships based on fear. However, she appears to be very attached to Denji. This is shown when she sees Yoru kiss Denji and calls her a "thief", showing her possessive nature for Denji's affection, and uses her devil powers on Yoru. She also resembles Denji, as she isn't very demanding, holds peace signs, and is content with basic food like sliced bread. Denji describes her as very smart.

Despite her blunt and serious nature, however, she does have a more childish side, evident by the fact that she has a monthly fart tally in her and Denji's apartment.

Abilities
As the Control Devil, Nayuta has the same powers as Makima, as shown when she is able to use the chain link ability. She also has all the standard devil abilities.
