Stella

Stella is an alien who entered the Syntharis Universe after their ship crashed. Stella used to lead the UFO with 3 other aliens, including her later surviving sister Astra, until a malfunction happened, causing the crash. After the crash, she and Astra were taken in by Jun Kangaru. She was not a problem, unlike Astra. But she grew wary of Wolfgang, and Tyrone, and especially stayed away from Fuka, not wanting to become her loyal pet. She had to often protect Astra because she gets into trouble a lot!
