Estellise Sidos Heurassein (エステリーゼ・シデス・ヒュラッセイン, Esuteriize Shidesu Hyurassein ?), better known as Estelle (エステル, Esuteru ?) , is one of the main protagonists in Tales of Vesperia.

Story Background
Estelle first encounters  Yuri Lowell  as they are both attempting to escape from the castle. She enlists his aid in her search for Flynn Scifo. Along the way, Yuri gives her the nickname Estelle. After reuniting with Flynn, she decides to continue traveling with Yuri in order to broaden her horizons. During their journey it is revealed that Estelle is both a princess and a leading candidate to succeed the throne. Unbeknownst to her, she also possesses the power of the "Child of the Full Moon", which grants her the ability to use healing artes without a blastia, drawing her powers directly from the world's aer.

Appearance and Personality
Estelle is an 18-year-old noblewoman who has spent all of her life growing up in Zaphias Castle. Due to her restrictive upbringing, she has gained most of her worldly knowledge through books. As a result she has developed a love for reading, and can recite various passages from heart. Proficient in healing artes, she was also trained in swordsmanship by a famed Imperial knight, Drake Dropwart. Despite her abundance of trivial knowledge, she has never left the castle and is sorely lacking in real-world experience. This becomes evident in her difficulty making critical decisions. Good-natured and selfless, she often puts others before herself. She uses her healing artes to help others whenever she can, and she is always kind to complete strangers.
