Osawari Tantei Ozawa Rina: Nameko Rhythm

A spinoff of the Touch Detective series, built around rhythm rather than mystery. Nameko—known as Funghi in Western releases—leads the rhythm while players tap the corresponding icons on the touchscreen in time to the beat. Hitting the right beats earns new songs and unlocks new outfits for Rina, giving the game a progression loop tied to performance.
