Grande Rosso is an AI that Hozuki created for the mechanic Galileo. It's designed to guide whoever's actually using the mechanic—like Hozuki Ferrari does.
The AI was inspired by Picco Rosso, a real goldfish that Hozuki used to visit regularly. Things got murky after the goldfish lost its home, so it's unclear whether Picco Rosso is even still around. You activate Grande Rosso by reading the manual aloud using a "Voice Recognition" technique.
