Demyx

Demyx the Melodious Nocturne (夜想のしらべ), is Rank IX within Organization XIII. He controls water, and uses his weapon, the sitar, as a musical instrument to make water fight for him in battle. He commands the Dancer Nobodies.

Demyx plays a minor role in Kingdom Hearts II, where he is tasked with tracking down Sora to liberate Roxas' "true disposition". Although he dislikes fighting, he is directed to use "aggressive tactics" against Sora and his companions to bring out Roxas. Demyx is a playable character in the multiplayer gameplay of Kingdom Hearts 358/2 Days.

Kingdom Hearts novels
In his own room at an unknown time, Demyx was fixing his hair in front of the mirror, something he did from when he was a human made him do it. Finishing setting his hair, Demyx picked up the sitar and strummed it. He plays and plays, but he was interrupted by Xaldin, who told him to keep it down because he wanted to sleep.

Annoyed, Xaldin questioned why Demyx clings to his human memories, but he didn't reply. Xaldin told him that Nobodies need to sleep because a terrible force is moving this world and they need rest to store up power. Demyx did not reply once again as Xaldin left the room, displeased.

Kingdom Hearts 358/2 Days
Demyx plays a slightly larger role in Kingdom Hearts 358/2 Days, present when Xion joined the Organization. Often teased behind his back by Axel and Roxas whilst they eat sea-salt ice cream at the Station Plaza after missions, they quote how he doesn't have talent, would be "upset" if he lost his sitar, along with many other things. Demyx is the first to mention the annihilation of Organization members that took place at Castle Oblivion, accompany Roxas on several missions including one to Olympus Coliseum, where they take down a Flare Note, and one to Halloween Town where they tackle a Dual Blade. Demyx enjoys picking on Xion with Xigbar, seen playing his sitar on one of the couches in the Gray Room before many of Roxas' missions. When Roxas approaches the Melodious Nocturne, he willingly admits that he "isn't cut out for missions," and would rather stay at the Castle That Never Was.

Hollow Bastion
Demyx appears in Hollow Bastion with all of the other Organization members, but he does not contact Sora. However, you can hear Demyx's higher-pitched, nervous laugh in the background.

Role in the Organization
Demyx's role in the Organization's plans is minor. He is sent after Sora on suggestion by Xigbar to find him and "liberate his true disposition", that is, to keep Sora on the path Organization XIII wish him to take. He also contacts Hades, but no deal was made and Demyx promptly flees, saying "Run, run away!", passing by Sora and co. and leaving them puzzled at his outburst. Later, Demyx steals the Olympus Stone, and soon encounters Sora within the Underworld once more. Although Sora doesn't understand the meaning of Demyx's objectives, nor why Demyx calls him Roxas, Demyx is unable to fulfill them and took the next ordered step, which is to attack Sora. Demyx at first only summons "forms" of water - water shaped into himself and musical notes, which then attacked Sora, Goofy and Donald - which he controlled with his sitar. He is unsuccessful in defeating Sora with his water forms, however, and escapes instead of continuing the fight.

Death
Demyx confronts Sora later in Hollow Bastion during the Battle of 1000 Heartless, again greeting Sora in a rather friendly manner. However, Sora and his companions' response is hostile, even claiming that Demyx is unable to fight. Demyx still maintains his personality despite the insult, with only a "You shouldn't judge anyone by appearance" in a slightly deeper tone. But when Sora and co. claim that the Nobodies do not have hearts, Demyx's normal carefree air vanishes, and he silences them with a much darker tone and attacks the "traitor" again with all his strength. In the end, however, Demyx is defeated again and fatally wounded. After lamenting his loss, he fades into darkness, the first Organization XIII member to do so in Kingdom Hearts II.

Personality
Demyx, unlike the other Organization members, has a very casual, friendly personality but also cowardly demeanor, though this is simply an act since Nobodies are free of all emotion and thus cannot feel fear. He runs from many encounters, including ones with Hades and Sora, and in 358/2 Days, he states that he finds Larxene quite frightening. Along with Xigbar, Axel and Larxene, Demyx is portrayed as one of the more comical members of the Organization although unlike the other three who have that role due to their sarcasm and wisecracks Demyx has this role because of his clumsiness.

With his friendly personality, Demyx seems to be good friends with both Axel and Xigbar, calling Xigbar "Xiggy" and is often shown talking to him in the Grey Area. And though Axel and Roxas talks about him behind his back, Axel did defend him after Roxas comments that Demyx doesn't do anything.

Demyx seems to dislike working as much as he dislikes fighting, he even goes as far as dumping his missions on other members and going off to have fun. He complains about how he "isn't cut out for missions", he often wishes that Xemnas wouldn't make him fight and how he'd prefer to stay at The Castle Than Never Was. Demyx seems to have a strong dislike of Larxene, and when news gets back from Castle Oblivion, he seems to be glad that she has died. This simply could be that Larxene's power is over lighting, and Demyx's is over water (In the Kingdom Hearts: Chain of Memories manga, Larxene is killed by water on her while she is fully charged. It is unknown if Demyx is weak to lighting, since water conduces electricity.)

Demyx is much less serious and more carefree than the other Organization members, and seems to take his task of pursuing Sora lightly. He doesn't hesitate to read his orders aloud off of cue cards in front of Sora, nor complain about his distaste for fighting. His cries in battle after being hit are also more characteristic of "yelps" than those of the other members, and are exclamations rather than reactions. In his final battle against Sora, however, his true nature as an emotionless entity is revealed, proving that his light attitude is a farce. However, it is not yet known the real reasons behind it, or if it was also a farce in itself to look dangerous; though it is worth noting this doesn't occur until after Donald denies his claim about Nobodies having hearts. Usually Sora does not take him seriously unlike the other members, but in their final confrontation seems shocked at his turnabout.

Fighting Style and Abilities
Demyx, being a musician, uses music to control the water around him and to summon "water forms", objects shaped out of water into musical instruments or copies of himself, which move about the battle area to hit Sora, forcing him to defeat the forms in a certain amount of time to avoid an automatic loss. He can also summon violent geysers to erupt from the ground,forming strong streams of water which damage Sora and throw him into the air. His sitar is rarely used as a weapon, but most often used to play his music instead. Demyx does little fighting by himself, instead relying on his control of water to make it fight for him.

Weapon
Demyx is very open about his dislike of fighting, and prefers music instead. So, Demyx carries an enormous Sitar, named the Arpeggio, a stringed instrument similar to a lute or guitar, into battle. The Sitar itself is shaped like the Nobody insignia, in varying shades of blue.

With it, he can cause water to take the form of people and musical notes and "dance" to his music. Although not very useful in battle itself, it can cause some damage if swung around into an enemy. Mostly, though, he just uses its strings to control water and make it fight for him.

Playing as Demyx
In Kingdom Hearts 358/2 Days, Demyx fights with his Sitar to perform long, multiple-hit combos that leave enemies open to other, more powerful attacks. Via the Gear System, Demyx can be customized along with all other playable characters, attacking in combos that leave enemies vulnerable to other players' attacks. During his Limit Break, Wave Gigs, Demyx jams on his Sitar, summoning up large pillars of water to rise and strike enemies. Enemies that are hit by the pillars take Water damage. During Demyx's Final Limit, Demyx releases a large ball of water while playing Arpeggio. The ball creates a watery explosion that knocks enemies back and again deals water damage.

Trivia

 * In Kingdom Hearts 358/2 Days he calls Xigbar "Xiggy".
 * Demyx makes a reference to Rip Van Winkle when talking about Xion's deep sleep in Kingdom Hearts 358/2 Days.
 * Demys technically swore in the Kingdom Hearts 358/2 Days manga, saying "craaaaaap" after hearing that the Castle Oblivion team were terminated. Xigbar replied by saying sarcastically, "nice language".
