PRAGMATA immerses you in a sci-fi lunar station crisis, where voice acting brings depth to its core characters. While Capcom has shared some official details, the cast focuses on key roles driving the story of survival and escape.
PRAGMATA characters and their roles
Hugh Williams anchors the narrative as the playable human protagonist, a dispatch team member separated during a lunar quake. He relies on wits, a customized spacesuit, and dry humor while lacking technical skills.
Diana, the mysterious android companion, rescues Hugh and enables hacking and support mechanics. Crafted from revolutionary Lunafilament tech using lunar ore, her childlike form hides enigmatic origins central to the plot.

Idas (also called IDUS) serves as the rogue AI antagonist, turning the station hostile and creating environmental threats. It drives conflict as the duo fights to defeat it and return to Earth.
Cabin acts as a support NPC, managing shelter maintenance as an independent AI ally in your journey.
