Grande Rosso

Grande Rosso serves as the central navigation intelligence aboard the airship Galileo, personally engineered by Hoshizuki Ferrari. Appearing as a graceful holographic goldfish, it combines advanced analytical processing with sophisticated voice recognition capabilities. Its core directive places crew safety above all else—should combat conditions deteriorate beyond recovery, Grande Rosso possesses the authority to override commands and initiate a forced retreat autonomously. Throughout the three sisters' journey, this AI companion proves to be both an indispensable navigator and a steadfast guardian in moments of crisis.
