Clover is the wealthy (former) heiress of the incredibly powerful Vermillion family. She's charismatic, elegant, and a true upper-class lady.

While she has no problem making a good first impression, she is very shy and can be a bit of a crybaby.  She's a bit arrogant, however, she is very sweet and loves her family with all her heart. She greatly admires her older sister Lotus and aspires to be just like her someday.

She meets Valerie by chance after hearing the shocking news that her sister, Lotus, had quit her modelling career. After her sister is attacked by the Nightmare Agency, she transforms into the Crystal Warrior of fantasy and starlight, Amethyst Heart, in order to protect her.
