Estellise Sidos Heurassein

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

History
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.

After hearing about the threat of the Child of the Full Moon by the elder in Myorzo, Estelle leaves the group with Raven following after her. She is later caught by Alexei Dinoia and used as a weapon against her friends and was taken to Zaphias. After a failed rescue attempt, she fell into despair and her power took control over her. Under her trance, she fought against her friends and pleaded them to kill her. However, thanks to some encouragement by Yuri, she was able to come back to her senses, but not before her power went out of control without Alexei controlling it. The others then pulled their strength together and brought Estelle back.

A sidequest in the game revolving around the Tree of Halure reveals that Estelle had chosen to live in Halure and write children's stories after her journey was over. In the end credits, Estelle can be seen reading to children, as well as finishing and closing a book she had written herself. In addition to her skill with stories, Estelle is skilled at naming things based off the things she has read. Throughout the game, she named Karol Capel's guild "Brave Vesperia", the elemental Spirits, and the town of Aurnion.

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.

Fighting Style
Estelle wields swords, staves, and shields in battle. Estelle is a highly effective healer with both target-based and area-based healing and support artes. Unlike the typical cleric archetype, she possesses a high defense and a large amount of defense-related skills, and can hold her own in the frontlines as an effective melee character with an emphasis on tanking enemies. She is also capable of using light-based magic, such as Holy Lance and Photon.

Party
Yuri Lowell - Estelle and Yuri get along very well, despite their different backgrounds and Yuri's dislike of the upper class. Throughout the game, Yuri's "street smarts" tend to clash with Estelle's "book smarts," shown by her attempts to get Yuri to actually read a book, which Yuri does not like doing, and the different way they deal with situations. It is not clear whether or not Estelle's feelings towards Yuri are romantic or sisterly in nature, but the two do share a close friendship and Estelle often expressed her joy at being able to travel with Yuri and the rest of the party. It is, however, speculated that the relationship between Estelle and Yuri is romantic rather than that of siblings. There are several moments throughout the game that display their relationship as romantic. Towards the end of the game, Estelle states that she is excited about being able to stay with everyone "especially" Yuri.

Rita Mordio - Estelle cares for Rita a lot. Rita also cares for Estelle, and is very protective of her, though she often denies it. Although, Rita is much closer to Estelle than she is with any of the other characters. This is obviously the result of Estelle's attempts at befriending her throughout much of the game.

Patty Fleur - Estelle and Judith both consider Patty a "very cute child", and Estelle acts somewhat like an older sister to Patty, being very supportive of her throughout the game. The two often talk, and can sometimes can be seen playing together after battles. After Patty recovers her memories, she cries when forced to kill Seifer, and Estelle is the first to comfort her.

Tales of Graces
During the Lala Sidequest, Estelle is one of the nine dolls that can be given to the sick girl. She is made by dualizing Hubert Ozwell's Family Coat of Arms and a Stuffed Toy.

Tales of the World: Radiant Mythology 2
Estelle appears as a playable character in Tales of the World: Radiant Mythology 2. She and Yuri arrive on the Van Eltia after a certain amount of missions are completed. Estelle serves no actual purpose in the main story, but she can be recruited for missions. After Goede is finally defeated, she and Yuri are on the Van Eltia looking at the mana spreading across the world. Unlike Yuri, Estelle actually retains a good fraction of her artes from her original game.

Tales of the World: Radiant Mythology 3
Estelle reappears as a playable character in Tales of the World: Radiant Mythology 3 along with fellow Vesperia characters Yuri Lowell, Flynn Scifo, Rita Mordio, Raven and Judith. She is first seen being cornered by Saleh, where she is aided by Mint Adenade, Shing Meteoryte, Veigue Lungberg and the Protagonist. During the same scene, it is discovered that she was separated from her group, and that Yuri and Rita were looking for her. She has access to many more artes in her original move set than in Radiant Mythology 2.

Project X Zone
Estelle appears in the crossover RPG Project X Zone as Yuri's partner ally. Unlike Yuri, she can not be damaged by enemy attacks. Outside of battle, she can use healing magic such as Nurse to recover every active unit present, as well as Dispel to remove ailments. She retains Sacred Blame as her mystic arte and uses it during a map attack. At the end of Yuri's Savage Wolf Fury, she uses Holy Lance to finish the enemy.
