Scarlet, crown princess and heir to Orvelia's throne, possesses long silver hair often styled in a braided bun with face-framing strands and striking blue eyes. She stands 168 centimeters tall. Her distinctive attire combines a black sleeveless dress layered beneath a white dress featuring petal-shaped flounces, accented by silver armor linings and diamond-shaped buckles. She accessorizes with a silver tiara and a unique black spiderweb-patterned necklace centered by a blue diamond-shaped brooch. Her ensemble includes black thigh-high stockings with garters, silver stiletto heels, bulky silver gauntlets over black sleeves, and gray-and-black armored gloves.

As daughter of current monarch King Veroglance the Second, Scarlet faces deadly opposition from the noble faction known as the Deadly Decadent Court. She survives an assassination attempt orchestrated by the prime minister and nobles who frame Aisha's family, protected by knights Clause, Demia, and Chase. Aware of potential heir Kasel, she is approximately one month his senior despite descending from his ancestor King Kyle.

Leading a military expedition to Gallua Plains in response to demonic activity, Scarlet encounters the vengeful dark elf Riheet pursuing wizard Malduk for slaughtering his mercenaries. She permits Riheet to join her forces. After defeating Malduk at the World Tree and battling the resurrected Dark Lord Angmund, Scarlet offers Riheet nobility. He declines, requesting instead the revelation of his ancestor Illya's truth to foster peace between dark elves and Orvelia—a request Scarlet honors.

She values honest and just individuals, disdains opportunists and oppressors of the weak. Her birthday falls on September 12th or 21st in the Month of Truth under the constellation Judgment Layan.
