Nagi Arisuin/Relationships

Shizuku Kurogane
Nagi and Shizuku seem to have a very good relationship with each other. Nagi is her friend, and they seem to be close to each other, with Shizuku accepting Alice as a transwoman, and as Alice doesn't care if Shizuku is in love with her own older brother, in fact, she encourages it. It is also stated, by Ikki, Shizuku usually never gets close to anyone, so for Nagi and her to have such a relationship is truly amazing.

Nagi and Shizuku's relationship is proven even greater than just a simple friendship as Nagi sees Shizuku as her little sister, something that she hasn't felt in a long time. Nagi cared so much for Shizuku that she was willing to betray the very man who took her in.

Ikki Kurogane
Nagi and Ikki have a friendly relationship, and Nagi describes Ikki to be exactly as what Shizuku made him out to be, kind. Nagi is also serving as a sort of adviser to Ikki over certain issues.

Stella Vermillion
Although Nagi and Stella haven't interacted much they seem to have a friendly relationship.

Kagami Kusakabe
Nagi and Kagami seemed to have a really strong relationship with each other as they seem to always gossip and talk every day. However, this seemed to be a façade by Nagi, who seems to think very little of the girl, even willing to kill her at a moments notice without any hesitation whatsoever.

Wallenstein
Nagi had mixed feelings toward her master. Nagi seems to be very loyal to Wallenstein after the incident with the government and their hiring of the local thugs. After which Wallenstein had taken Nagi in and they had begun a student master relationship with each other. Wallenstein seems to hold in high regards upon noticing Nagi's potential as an assassin despite her age.

Wallenstein becomes distraught and enraged after noting her sudden change due to her not going along with the plan of destroying competitors from Hagun Academy who Nagi had also grown close to, as Wallenstein even going as far as started beating and stomping on her while being tied up in front of him, then started to fight Shizuku in front of Nagi.

Yuuri
Yuuri was Nagi's dear friend during their childhood. They were both orphans, who looked after other younger orphaned children. Nagi and Yuuri were almost complete opposites, with Nagi being very calm and full of gentleness, while Yuuri was lively and full of unyielding spirit. Yuuri's death was a very traumatic experience for Nagi, and a major reason for Nagi joining Rebellion.
