Chastel Aiheap (シャスティル・アイヒープ Shastir Aihiipu?) is a major character in Tales of Vesperia: The First Strike. She works for the military as a knight within the Niren Brigade, serving alongside Yuri Lowell, Flynn Scifo, and her older twin sister, Hisca Aiheap.
Chastel is first seen with Flynn setting blastia traps while being chased by a large pack of monsters. As they regroup with Hisca, Yuri, and the other teams dispatched on the mission, Hisca uses Force Field just as captain Niren Fedrok activates the blastia from afar, obliterating the monsters.
The next morning, Yuri asks Hisca to show him how her Bodhi blastia works, since rookies are not given any, but they are quickly caught by Niren, who has just returned from the forest. When the aer goes out of control near their post, Chastel accompanies Niren to the laboratory of Rita Mordio, who provides them with information about the current situation, as well as gives them a blastia that will absorb the aer and prevent any blastia equipped with it from overloading. While Chastel does not appear in the original Xbox 360 release of Tales of Vesperia, she was exclusive to the PlayStation 3 version and Definitive Edition as part of a sidequest.
Appearance and Personality
As a twin, Chastel shares Hisca's red hair and yellow eyes, but Chastel's chest is more enveloped than her sister's. Chastel is more gentle than the stubborn Hisca.
