Ikki Kurogane/Relationships

Stella Vermillion
Ikki's roommate, the two started off with a rocky relationship due to Ikki accidentally seeing Stella changing and Ikki suddenly stripping to (unsuccessfully) even the situation. After their mock duel, Ikki and Stella start to become closer, becoming good friends and rivals. Despite being initially unaware of her feelings of affection towards him, Ikki admits to himself that he respects Stella as a knight and also finds her extremely attractive. During Ikki's debut battle against Shizuya Kirihara, he nearly broke down due to mental stress and constant discouragement by the audience. At that moment Stella screamed encouragement towards him, suddenly confessing her feelings. This gave Ikki the motivation and courage to see through his opponent's attacks and easily overcome him. Sometime after his victory Ikki woke up after collapsing from his injuries and fatigue, and found out that Stella had stayed with him ever since, where he then confessed his feelings for her. Stella accepted his feelings along with a promise to battle him once the festival is over without losing to anyone else up to that point.

Shizuku Kurogane
Ikki's sister. Shizuku is the only family member that didn't discriminate against Ikki, thus the two have a close relationship. Shizuku, however, sees Ikki as more than a brother, a feeling that Ikki does not share and is admittedly disturbed by her actions that crosses sibling affections.

Yuuri Oreki
Ikki and Yuuri are on good terms with each other. Ikki is thankful to Yuuri for her unbiased view towards him during his entrance examination day. He also shows understanding towards Yuuri, knowing that she was pushing herself so that the new students don't feel tension.
