Kaoru Koganei

This character, known as Lady Diamond, possesses the incredible ability to transform her body into diamond, granting her near-invulnerability, and she can use her nails as weapons. She has a peculiar fascination with diamonds, even consuming them, stemming from a tragic past involving her husband, an artist who gifted her jewels before his suicide. Now, she is driven by an intense desire to embody the dazzling monument of his love through her own diamond form.
