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, as Shizuku does not care if Nagi believes himself to be a girl, and as Nagi doesn't care if Shizuku is in love with her own older brother, in fact he encourages it. It is also stated, by Ikki, Shizuku usually never gets close to anyone, especially someone of the opposite sex, so for Nagi and her to have such a relationship is truly amazing.

Ikki Kurogane

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