Tooru is a gray American Shorthair cat who embodies adventure and wears a distinctive green star necklace. He first showed up in Episode 10 as Ruby's boyfriend in Season 1, and later returns in Season 2 as Sulfur's Jewelpet partner.
He's got that aristocratic, charismatic charm going for him—the kind of cat who's genuinely kind to everyone around him, though Ruby seems to get the most attention when he's nearby. Fans often note how she calls him "Tooru-sama" early on and gets flustered whenever he's around. Beyond the charm, he's actually a capable adventurer with solid reflexes and an impressive somersault technique.
In Jewelpet Tinkle, he continues as Sulfur's partner and even pulls Ruby out of the water in one episode. His name comes from the jewel tourmaline.
