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.

Ikki then goes to the pool to train Ayase, and as the day progressed, Ayase decides to push Stella and Ikki's relationship by leaving them alone togeather. After an awkward conversation, and yelling, Ikki and Stella then go to a more private place, where Ikki and Stella are finally able to solidify their relationship as they are able to kiss each other, twice on the lips.

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

Nagi Arisuin
Ikki and Nagi are shown to be on good terms with each other with Nagi serving as a sort of adviser to Ikki over certain issues.
