Amane Shinomiya/Relationships

Ikki Kurogane
Amane is a big fan of Ikki, adoring him greatly. Amane has records of all his battles and has even memorized all of his catchphrases. The reason for Amane adoring Ikki, is that he enjoys his continues battle against unbeatable odds, giving his all when fighting fate itself. Amane, in fact, wishes to see Ikki continue his endless struggle until he dies. Ikki finds Amane's adoration weird and unnerving, eventually even despise him, due to Amane's cruel and emotionless nature.

During the match between the two, Ikki used information about Amane's past that he received from Tsukikage, to provoke Amane. This draws out Amane's anger, turning against Ikki with all of his hatred. After his defeat, Amane seems to give up on his twisted ways, not having any reason to continue on.

Shizuku Kurogane
Shizuku views Amane very negatively, wanting to protect her brother from him, and being even willing to break the rules of the Festival, to make sure Amane can't face Ikki. Amane treats Shizuku very cruelly, revealing her love of Ikki to the whole world, without a shred of hesitation.

Stella Vermillion
Stella initially thought that Amane was a bit weird, though nice. However, after Amane reveals his true nature, Stella begins to view him with disgust and hate.

Akatsuki
Amane doesn't care much about the Akatsuki members, though he does follow the rules given to him, and will fight for the benefit of the group.

Parents
Amane lived his early life with his mom, who seemed to love him much. However, she actually only cared about Amane's abilities, and when he stopped using them, she lashed out against him. Amane's father killed her mother to "save" him, but Amane realized that he too only cared for his power.

Edelweiss
Edelweiss met Amane when he was young and abandoned. Edelweiss wished to help him, and brought him to Rebellion, as she saw that Amane didn't want to live on the light side of the world. She was sad that she was unable to do more. Amane's view of Edelweiss is unknown.

Kiriko Yakushi
Amane used his ability to force Kriko to withdraw from the Festival. Due to this, Kiriko later healed Ikki, from damage that Amane himself caused, as revenge.
