Shizuku Kurogane/Relationships

Ikki Kurogane
Shizuku's 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.

Nagi Arisuin
Shizuku's roommate. Arisu is the only person Shizuku has open to aside from Ikki despite her misanthropy resulting from Ikki leaving the house.

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