Kaito's childhood friend who sticks with him through basically all his puzzle-solving adventures. She's genuinely athletic and talented at sports, plus she's got a photographic memory—which sounds like it'd make her amazing at puzzles, but that's not really her thing. Where she really shines is baking. Her sweets are legitimately delicious and everyone loves them. except Kaito, who's somehow terrified of eating anything she makes.
Things took a weird turn when she helped some kindergarteners work through a puzzle. Next thing she knew, she'd been given the title "Nightingale," which honestly threw her for a loop. She's always thought people with titles were total weirdos, so becoming one herself felt pretty ironic.
