Nova Galara is an explorer for Galacta, an intergalactic agency dedicated to exploring planets to fill up their Celestipedia of Planet information. She is armed with a cybernetic sword and her "Star Cannon" (An equippable arm cannon) for self defense. She's kind and compassionate, but easily gets nervous, but also gets really serious in combat. She knows of the rumors about Galacta's secret plans with the Celestipedia, but doesn't want to believe them.
