Counterpoint

 The Counterpoint is a Keychain for Sora's, Riku's, and Player's Keyblades that appears in Kingdom Hearts 3D: Dream Drop Distance and Kingdom Hearts Union χ.

Design
The Counterpoint's design varies depending on its upgrades, most of which are only seen in Kingdom Hearts Union χ.

The default Counterpoint has a dull bronze guard, which is modeled after a member of. The blade is a slightly stylized line of music, colored in light green with golden s. The teeth are composed of a with a light green color scheme that fades to indigo, and is topped with a small version of Yen Sid's hat and a four-pointed star. The Keychain is comprised of silver stars, with the token being a lime-green to blue stylized eighth note and a silver star.

The first upgrade, also seen in Kingdom Hearts Dream Drop Distance, has a more defined bronze guard. The blade is now a brilliant blue that fades to cyan, with the base being a semicircle with a golden star inscribed. The treble clef is predominantly magenta, and the star on the hat is now a larger, five-pointed star. The Keychain's links are silver and golden, while the token is magenta. Like all Keyblades in Kingdom Hearts Dream Drop Distance, this upgrade adopts a dark blue color scheme with light blue accents while in The Grid.

The second upgrade's guard is indigo with more starry features, much like the Star Seeker. The blade is golden with red, magenta, and aquamarine notes. The treble clef ranges from blue to magenta, and the hat's star is now a sun.

The third upgrade cloaks the Keyblade in a pink aura, with yellow and pink lens flares near the guard and a green lens flare near the teeth.

The Keyblade's English name references a, the relationship between voices that sound different individually but are harmonious when played together. The Japanese name alludes to the Sound Ideas found in the Symphony of Sorcery.
