What it does: The Clashing Harmony comes in the form of both a flute and the normal psychic device orb. She wears the orb on a breastplate tipped with spikes, and uses the flute as you would a normal one. This flute can also be used for hand to hand combat, such as using it to defend against an opponent's sword. She is able to collect energy in the form of sound waves and release it to strike the enemy when she plays the different songs. Here are the songs/attacks she uses( I don't know how to spell certain songs as I couldn't quite catch the names, so if the spelling looks really weird, don't kill me. ^_^ Email me at firetigeress@yahoo.com if you know the proper names):

Prelude
A shockwave of sound energy. If I'm not wrong, this is the move in which Neon used to create a huge hole in the ground. (Or was it Rhapsody?)

Rhapsody
This is the move where Neon condenses energy, then detonates it as she would a bomb.

Concerto
(For some reason, I heard them pronounce it as "Concheerdo". Is that the proper pronunciation?) She sends a blast towards Miki, and Miki reflects it back with the Echo Shield, attacking the enemy unexpectedly from behind. This is very useful, since the enemy doesn't suspect the energy to come rebounding back towards him. However, the timing and syncronisation between the two sisters must be very precise - if Miki is not careful and puts up her shield too late or two early, or in the wrong position, she might get hit by the attack instead.

Fugue
A chunk of sound. I don't know much else about it, really. I'll have to go watch that episode again...

Requiem
This is a move which sends all living beings to death. She needs some time to collect all the necessary energy first, though, and this makes her very vulnerable to attacks from enemies. To amend this, she creates a green bubble barrier around herself, although this can still be pierced through.

Highlight below for volume 23 spoilers. (FoR season II)

Later on, when everyone is preparing for the final confrontation against Kouran Mori, Neon visits the (destroyed) Dark Martial Combat Arena again, and finds Jishou's N and S blades. This she will use to fight against Mori, I think.

The N and S blades work in the same way as magnets. The user throws the N blade far away from the enemy, which will catch them off-guard since they think that he/she has missed his target. However, this is proved wrong when, by saying the words, "Come before me. S Blade!" the N blade comes whoosing back, piercing through the enemy from behind.
