Kurosaki Mea/Relationships

Golden Darkness (Yami)
Like Yami, Mea is a transformation weapon that was created by Tearju. Though not alsocreated from Tearju's DNA, she is still considered to be their younger sister. Mea came to Earth by orders of her master Nemesis to bring Yami back into space as her cold-hearted assassin old self and wants her to be the ultimate weapon that is unstoppable by anything and anyone, but Yami encouraged her to try and embrace humanity, which she slowly does with the help of Rito, Tearju, Momo and Nana. Yami shows a slight care and understanding towards Mea.

Tearju Lunatique
Tearju is Mea's creator. As stated by Nemesis, Tearju is the "barrier" for Yami to become her cold-hearted old self, which is why Mea wants her out of the way, but Tearju considers her a sister like Yami, which she rejects.

Perhaps because she feels able to find a sister and family in an assassin like Yami to ease the loneliness she denies having, she rejects Tearju, whom she cannot accept as her family without betraying her stubborn belief that she is a weapon.

As of To Love-Ru Darkness chapter 30, Mea has begun to allow Yami to reunite with Tearju. But she still maintains her reluctance to become closer to Tearju.

Nemesis
Nemesis was the first person Mea ever met after waking up. Nemesis guided Mea and teaches her what it means to be a transformation weapon and about who Yami is. Mea looks up to and trusts Nemesis, calling her master and gets mad at anyone who disrespects her in any way. It is Nemesis' teachings and Mea's strict adherence to them that put her directly at odds with the other characters of the series, and the friendships they offer to her.

Mea would become uneasy when Nemesis is not there to help her reaffirm her beliefs by reminding her not to be swayed by friends. However, Mea has decided to think more independently and become more open and understanding with her newfound friendships, which her master has decided to permit.

Mea appears capable of a transformation which turns her hair black and her eyes bright yellow, making her look more like Nemesis. It is hinted that, during this form, Nemesis possesses her and uses her as a vessel.

Rito Yuuki
Mea is interested in Rito especially when Nana told her that he is a beast. Mea has a desire for Rito to lick her body and at times teases him by asking him to do it to her despite being in front of people. One time, Mea got mad at Rito for questioning her master and tried punishing him by using her pony tail to control his movements and actually forces him to lick her. While their thoughts and feelings are synchronized, Rito notices a feeling inside her, saying it's "like a lost child all on your own", which she angrily denies.

On some level Mea slightly cares for Rito, she even continues to toy with his shyness and tries to do lewd things with him, although it's unknown if it's love or lust. Rito truly cares for Mea and tries to make her embrace humanity, which she slowly begins to accept. After having spoken to Rito, Mea allows Yami to reunite with Tearju, and even assists Rito in convincing her to attend school again, grudgingly accepting Rito's advice about filling the gap between them.

She once mentioned to her master Nemesis that Rito is a fool for easily trusting, she also thinks of him weak, although Mea is curious to see how far a weak earthling would go in helping others against more frightning foes.

Nana Aster Deviluke
Nana is the first friend Mea made when she came to Earth. They seem like best friends. Nana introduced Mea to some of her animal friends, and Mea even tried to save Nana from an oncoming truck.

Once Nana saw Mea in her semi-weapon form, realizing she's just like Yami, Mea states that their friendship was all a lie. Nana felt saddened and heartbroken by this. Rito encouraged Nana to fearlessly embrace Mea to prove to her that it wasn't a lie. In the end, Mea accepted it, and they became friends again.

Momo Velia Deviluke
Mea gets on Momo's nerves when she interferes with her plan to make Rito's harem, even when talking about it around others. But other than that, they get on good terms, and hang out together with Nana on some occasions. They are also similarly perverted whenever Rito is involved, like how when Momo tries to bring Run closer to Rito they both get excited and imagine an ecchi moment is going to happen to them, and  they both even enjoy licking on Rito's female body.

Oshizu Murasame
Oshizu was one of the girls who knows about Mea's true self. While wanting to get more information on Mea and her Master, she took possesion on her to find anything important. As Oshizu dived deeper inside Mea's mind, she discovered a deep darkness that almost consumed her making her to unable to trust Mea.

After seeing Mea convincing Yami to open up with Tearju, Oshizu starts seeing a kind side of Mea and considers to become friends with her. She starts following her and ends up getting teased by Mea. Irritated, she said that she hates her but Mea replies that she does not hate her, as Oshizu was easy to be teased and how she feels comfortable to be her real self in front of Oshizu.

Oshizu asked her why she hides her identity even when she was comfrotable with it. Mea tells Oshizu that acting as an earthling is no use no more but at the same time, she does not want to discard her identity as Kurosaki Mea. She has shown some care for Oshizu as she help her destroy a black hole before her spirit has completely disappered with the latter reveling her true identity in Darkness Chapter 37, they have also become closer friends but Mea likes taking adventage of her power and fear of dogs which causes something ecchi to happen.
