Nemesis/Relationships

Mea Kurosaki
Mea is another transformation weapon and Nemesis' personal spy whom she used to watch over Yami. Both she and Mea share a close relationship. Mea is very obedient to her as she is the first person to confront her after the end of the Galactic War. However, it is not known how much Nemesis truly cares for Mea. Although she ultimately permits Mea to pursue her friendships on Earth, Nemesis previously persuaded Mea that her nature as a weapon is to ultimately be heartless and alone. And Nemesis seems to choose not to inform everything she knows to Mea, such as the true nature of the "Darkness" ability inside Yami.

In Darkness Chapter 40, Nemesis claimed that Mea is alternate personality that Nemesis created, which Mea remain denying it.

Yami (Golden Darkness)
Yami is a transformation weapon like Nemesis, and the center of Nemesis' plans. Nemesis and Yami seem to know each other, though they meet each other for the first time in Chapter 23-24. Nemesis originally planned to convince Yami to return to her old life as an assassin, but revealed that her true objective is to make Yami use a transformation ability called "Darkness" (an ability unique to Yami) and with it, she believes that Yami will naturally revert back to her old self.

Tearju Lunatique
Nemesis and Tearju seem to know about each other, but unlikely have met each other in the past. Nemesis states that Tearju is the "barrier" to her and Yami. The two officialy meet in Darkness Chapter 40.

Rito Yuuki
Originally Nemesis planned on having Yami finish her previous job to kill Rito, until she notices how he is the human who draws both Yami and Mea to humanity. As such, to observe more closely how their lives progress, she decides to become friendly with him, in her own erotic way.

She seems to be very (sexually) interested with Rito, and finds his nervous expressions towards her arousing. In her first appearance, she offered to train him to be her 'pet'. She playfully considers him as her servant, and essentially enjoys treating him as her boy toy.

Momo Velia Deviluke
On first meeting, Nemesis plays with Momo's tail weakness in front of Rito and decides that she is worth torturing as well. They both share erotic and mischievous tendencies especially towards Rito, something they can relate to, but her's are so strong and sadistic, even Momo has considered her a threat.

Despite Momo's plan to build a harem of girls around Rito, Nemesis is apparently the only female whom Momo does not want near Rito, and apparently the only one who can stir up feelings of jealousy in Momo, other than Nana as seen on several occasions. Nemesis very much now enjoys getting on Momo's nerves, and Momo considers Nemesis her natural enemy. She even told Momo to give up on the harem plan because she wants Rito all to herself as her servant.
