Rasati is Lillia's older sister and a skilled martial artist who frequently competes in tournaments against Edel Raid Pleasures, managing to defeat them without possessing an Edel Raid herself. She is fiercely protective of Lillia and looks down on Pleasures for using Edel Raids as "weapons," given that her sister is one. Rasati relies on Ki-based attacks and sheer determination. She has a tomboyish personality and is usually serious.
Lillia, being an Edel Raid, was purchased by the arena manager from Rasati's uncle. To free both sisters from debt, Rasati became a determined fighter, dedicating all her winnings to paying off Lillia's debt.
In the anime, she primarily appears during the arena arc with some minor roles later on. In the manga, however, the sisters continue to travel with the main group for a considerable period.
After Ren explains that fighting with an Edel Raid means fighting together rather than using the Edel Raid as a weapon, Rasati and Lillia react to gain a leg blade capable of shooting out energy.
