Galileo Galilei
An astronomer and the ancestor of the Ferrari sisters. When the Galileo Tesoro activates, Hozuki gets thrown back in time and meets him—and he falls for her almost immediately. Unable to confess his feelings after she returns to her own era, Galileo did the next best thing: he encoded love letters into his moon sketches, hoping she'd eventually find them centuries later.
Fans often note that Galileo shares Hozuki's taste for confetti, which becomes a sweet detail connecting them across time.
Personality-wise, he's genuinely kind and sharp, though he struggles with self-confidence and expressing himself. His time with Hozuki actually changes him—she gives him the courage to speak up and believe in himself. It's basically a romance that transcends literal centuries, written in the margins of astronomical observations.
