Stella (Chivalry of a Failed Knight)

How Stella joined the Tourney
The main heroine of the series, Stella is a red-haired A-Rank Blazer who is considered to be a once-in-a-decade genius. Her Device is Laevateinn and her Noble Art is Katharterio Salamandra. The second princess of the Vermillion Kingdom (a small European country), Stella could not control her own powers as a child and was badly burned each time she tried to use them. Through her effort, she eventually mastered her own power and is widely regarded as a genius by those around her. Not wanting to become conceited, Stella then decided to transfer to Japan. At the start of the story, she challenges Ikki to a duel where the loser must obey the winner, but she loses. Although they agree to be roommates, Stella feels it is her noble's obligation to treat him as a master. She is immediately jealous of other girls being affectionate towards Ikki, and over the course of the series, she falls in love with Ikki. They eventually become a couple and get engaged after both she and Ikki qualify for the Seven Star tournament.

With war declared on the Vermillion Kingdom, Stella is caleld to action to face Hinoka.
