JP name: Edge Marverick
Voice Actor: Kishio Daisuke (JP); Matthew Mercer (EN)
An honest young man with a strong sense of justice and responsibility. He volunteers for the maiden voyage of the SRF (Space Reconnaissance Force) to save humanity from the brink of extinction, electing to journey outside his solar system to the vast universe beyond. While he possesses superior circumstantial judgment, he tends to come off as reckless, and his jump-the-gun nature probably doesn't help matters. His childhood friend Reimi gives him and earful over it regularly.
Edge is the main character of the game and the one you control at all times.
Voice Actor: Misato Fukuen (JP); Laura Bailey (EN)
A young lady born into the illustrious Saionji household, Reimi has studied archery since childhood and now stands toe to toe with other masters of the bow. For all her kindness and consideration toward others, Reimi is extremely hard on herself, and sometimes the pressure gets to her. Like Edge, she was selected at a young age for the maiden voyage of SRF, and takes part in the journey into deep space. There, she serves the team as a level-headed navigator and a source of support for Edge.
Faize Sheifa Beleth
Voice Actor: Mitsuki Saiga (JP); Jason Liebrecht (EN)
A young man from the planet Eldar who belongs to a planetary exploration team. He considers etiquette very important and treats those with qualities he lacks with due reverence. He is a man of talent, able to wield symbols that other Eldarians would need a high level of study to master; he even designed on his own a small shuttlecraft for use in exploration. Faize is an extremely logical thinker, and takes on a harsh tone and hard stance toward irrational people, but at heart he's an affable, genuine sort of guy.

She's basically a pampered child who's fond of mischief; ever since a certain incident, she's closed the world out and continues to speak like someone younger than her age. Still, she's tough at heart and her energy keeps her standing tall even in trying circumstances.
