Hisca Aiheap (ヒスカ・アイヒープ Hisuka 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 younger twin sister, Chastel Aiheap. She often gets on Yuri's case due to his impulsiveness. Despite being identical to Chastel, the two have vastly different personalities.
Hisca is first seen with Yuri setting blastia traps while being chased by a large pack of monsters. As they regroup with Chastel, Flynn, and the other teams dispatched on the mission, Hisca uses Force Field just as Niren 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.
While Hisca 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, Hisca shares Chastel's red hair and yellow eyes, but Hisca's chest is more flat than her sister's. Hisca is more stubborn than the gentle Chastel.
