Shizuku Kurogane

Shizuku Kurogane is a key character in Chivalry of a Failed Knight (also known as Rakudai Kishi no Cavalry). She is the younger sister of the protagonist, Ikki Kurogane, and serves as the female deuteragonist.

She is a first-year student at Hagun Academy, ranked as a B-Rank Blazer (with exceptional A-Rank magic control), and her nickname is Lorelei (or "Deep Sea Witch"). Her Element is water, allowing her to manipulate it in versatile ways—including attacks, barriers, imprisonment techniques (like Water Prison Orb), and even healing. Her Device is called Yoishigure.

Shizuku has silver/white hair (contrasting her brother's black hair) and a petite build. She is deeply devoted to Ikki, showing strong (and often openly affectionate/incestuous-leaning) brother complex feelings toward him, stemming from being the only family member who supported and loved him despite the Kurogane clan's harsh treatment and rejection of Ikki as the "failed" F-Rank Blazer. She resents her family and the Kurogane name because of this.

Her personality is generally calm, composed, and feminine, though she can be fiercely protective of Ikki and competitive (especially toward rivals like Stella Vermillion). Over the story, she grows to accept Ikki's relationships and shows maturity in key moments.
