Mira Yamana/Relationships

Royal Biblia Academy
Arata Kasuga - As the head of Grimoire Security, Mira was initially hostile towards Arata, a Demon Lord Candidate, whom she viewed as an impure existence and needed to be destroyed. As such, in their first time meeting each other, she would order Akio to kill him to stop a Breakdown Phenomenon he was causing. Although later she would rescind her decisions, she still remained wary and unfriendly to him. However, despite her antagonist treatment, Arata wouldn't hold a grudge and continued to act casually around her. Eventually, though, she would gradually come to trust and accept him. When seeing her panties, Mira gets irritated and she beat's up Arata for his perversion. During their investigation in Royal Liber Academy, Mira after becoming unable to use her magic would come to rely on him, revealing her past and slowly open up to him. At one point, when she was about to be killed by Ilya, his helplessness to save her and Sora would cause him to transform into Astral Trinity. As Astral Trinity, seeing potential in her, he would demand that she submit to him. In which she would respond with a slap, stating that she had nothing to offer to anyone other than Arata, giving Sora the chance to revert him back. Since the mission, Mira has grown to care deeply for him, treating him more politely and worrying about his well being. She has fallen in love with Arata showing signs of jealousy whenever he interacts with other girls. Overall, the two of them become closer, respecting one another and becoming the will to fight for each other.

Trinity Seven
Akio Fudo -The current third seat of Grimoire Security, Akio is Mira's partner and closest friend out of the Trinity Seven. Prior to joining Trinity Seven and Grimoire Security, Mira was someone who couldn't assert herself, being very shy around everyone. Along with the fear of her very high magic hurting someone, she would avoid people and as a result became isolated. However, one day Akio would come and take her hand, giving her many new experiences. Akio would help inspire Mira to change, embracing her magic and becoming more confident. Eventually, Mira would join Grimoire Security as the head and the two would become partners to destroy Breakdown Phenomenon's. Currently, despite Mira's strictness personality and Akio carefree attitude, the two of them have a deep trust and respect for one another, being able to work together effectively as a team. Akio, in particular, doesn't mind her partner's sternness and is always willing to follow her orders. Although, she is sometimes surprised by the lengths Mira will go to complete her mission. Regardless, they both get along very well, almost always seen together even out of missions. Akio especially enjoys teasing Mira on her rather pure side. The two of them rely on and care very deeply for each other, always willing to fight and support the other. Even though Mira is technically her superior, Akio is always watching over her and sometimes console her whenever she disheartened. After Mira is no longer a Trinity Seven, the last person to see her was Akio. Akio also is the only person who knows Mira's real name as well after being informed. Even though Akio was worried about her and remembering her past with Mira. Still Mira doesn't regret what happened, and considers Akio her best friend.

Lilith Azazel - Lilith and Mira are good friends and comrades, respecting and trusting one another. As two of the more serious characters amongst their peers, they are often shocked or embarrassed by their friend's actions, usually having to be the straight man in many of those situations. Furthermore, although Mira's position as head of Grimoire Security occasionally puts them on opposite sides, this does not stop them from remaining friends. The both of them care and support each other, able to work together as a team during battles. Notably, before Mira joined Grimoire Security and Trinity Seven, Lilith would watch over Mira and try to help her after she became isolated due to her shy nature. Lastly, they are both hinted to have feelings for Arata, but they have not allowed this stop them from remaining on friendly terms.

Lieselotte Sherlock - Lieselotte was the former second seat of Grimoire Security, working together with Mira and Akio to destroy Breakdown Phenomenons until her disappearance. After Arata's transferred to Biblia, Lieselotte would reappear as an enemy before Mira and everyone, eventually nullifying their magic with the exception of Mira and Levi. Despite being former comrades, Mira, now viewing her as an enemy, would swear to eliminate her. Although, even with the help of Levi, their battle ended with a draw. However, regardless Lieselotte's betrayal, Mira would still care for her well being. After Lieselotte lost to Arata and became trapped, Mira would order Selina to help Arata save her under the guise of giving Lieselotte her punishment. Since Lieselotte's return, the two of them have remained on friendly terms, once more fighting on the same side.
