Harmonics

The Harmonics is a Sitar that can be wielded by Demyx in Kingdom Hearts 358/2 Days. It can be upgraded to the Harmonics+.

Design
The headstock of the Harmonics has an elegant, triangular design. There is a large gap in each of its corners, and it is silver. The neck of the sitar is long, grey, and has ridged, black edges. The body is roughly pentagonal in shape, and sports a small, semi-circular indentation in each of its two upper sides. There is a cyan diamond set in each of its lower three corners, and a grey one in each of its upper two corners. The body is predominantly blue, and has thick, black edges. The sitar has three white strings that are anchored to the body by a small, white triangular piece.

In acoustics, a is the frequency of the signal of a wave.

Gameplay
Harmonics's ground combo starts with a 360° spinning attack, after which, Demyx strums the sitar, emitting a yellow shockwave which damages any enemies around him, followed by a leap and a very fast airborne spinning attack, and ends by repeating the first move of the combo.

The aerial combo consists of a series of very fast airborne spinning attacks, followed by a blast of three yellow shockwaves forwards.
