Shizuku Kurogane/Relationships

Ikki Kurogane
Shizuku's beloved brother. Shizuku loves Ikki dearly as a child and was saddened when Ikki left the house and was shocked to see that her family didn't even show a hint of care. Following that incident, Shizuku decides to love him in the place of her parents, siblings, friends and lover.

Stella Vermillion
Shizuku and Stella are on extremely bad terms with each other, mainly due to the two of them being after the same man. Shizuku views Stella as an eyesore for loving and trying to take Ikki away from her, while Stella considers Shizuku a sick and dangerous sister who loves her brother incestuously.

Although these feelings of hate begin to change into feelings of respect and admiration, after the events of Rebellion's first attack, where she sees Stella was willing to be humiliated all for the sake of some random people, and was still able to beat the goons after being humiliated.

Nagi "Alice" Arisuin
Shizuku's roommate. Alice is the only person Shizuku has open to aside from Ikki despite her misanthropy resulting from Ikki leaving the house. Alice seems to also understand Shizuku on a very deep and emotional level, as she was the only one who was able to comfort Shizuku, when she had lost her match with Tohka.

Shizuku and Alice's relationship had grown to a point to where they see each other as sisters. Shizuku was even willing to risk her own life against an opponent she could not possibly beat all to save Alice who had just admitted to being a traitor to Hagun Academy.

Itsuki Kurogane
Shizuku doesn't like her own father, as he had been the cause of Ikki's disappearance. The regret in Shizuku's heart, of not knowing how Itsuki and the rest of the family treated Ikki, turned into anger at Iwao, who could not find any love for his F ranked son.

Mother
Although Shizuku is on bad terms with her father, she does not share the same feelings towards her mother and even returns home after receiving a letter from her and became all the more hateful towards her father as he execrably took advantage of Shizuku's positive relationship, with her mother, as Itsuki made his wife to write the letter so that he can see his daughter.

Ouma Kurogane
Her eldest brother. He has abandoned their family, thus no longer considers them as important.

Kiriko Yakushi
Shizuku admires Kiriko, who is one of the most skillful water users in the world, even better than Shizuku. Shizuku holds her in a high regard, even asking Kiriko to train her.
