Editing Demyx

'''Demyx''', the {{nihongo|''Melodious Nocturne''|夜想のしらべ|Yasō no Shirabe|lit. ''Nocturnal Melody''}}, is Rank IX within the original [[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.

On an unknown world, Demyx's original persona became a Heartless, his strong will allowing his body to continue on as his Nobody, Demyx. He was later located and inducted into Organization XIII as its ninth member, due to his connection to the ancient [[Keyblade War]].{{fact}}<!--cite quote, not storylink-->

Annoyed, Xaldin questioned why Demyx clung to his human memories but received no reply. Xaldin told him that [[Nobody|Nobodies]] needed to sleep because a terrible force was moving that world, and they need rest to store up power. Demyx did not reply once again as Xaldin left the room, displeased.-->

Demyx is present when [[Xion]] joins the Organization. Axel and Roxas often tease Demyx behind his back while eating sea-salt ice cream at Station Plaza after missions, quoting how he doesn't have talent, would be "upset" if he lost his sitar, and many other things. Demyx is the first to mention the annihilation of Organization members at [[Castle Oblivion]]. Demyx accompanies 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]], and is seen playing his sitar on one of the couches in the Grey Area before many of Roxas's missions. When Roxas approaches Demyx, he willingly admits that he "isn't cut out for combat" and would rather perform recon. He is shocked to learn of Xion's true nature when Xemnas describes the Replica Program to the Organization.

Demyx appears alongside [[Xemnas]], [[Saïx]], [[Xigbar]], [[Luxord]], and [[Xaldin]] at Hollow Bastion, and laughs emptily with the rest of the group at Xemnas's empty humor at Sora's expense. Upon the Organization's return from Hollow Bastion, he suggests to let Sora carry out his adventures and that they will take action at the right time. Xigbar pretends to interpret Demyx's suggestion as him volunteering, while Demyx responds by acting flustered at this imposition. Xaldin chides both of them for acting as if they have emotions, then Xemnas interrupts all three of them by instructing the Organization to create powerful Heartless for Sora to slay.

On Xigbar's suggestion, he is sent to the Olympus Coliseum in order to find Sora and either push him along the path Organization XIII wish him to take, or try to awaken Roxas. Demyx contacts [[Hades]] for his assistance, but no deal was made and Demyx promptly flees, passing by Sora and company, and leaving them puzzled at his outburst. Later, Demyx steals the [[Olympus Stone]], and re-encounters Sora, [[Goofy]], and [[Donald Duck|Donald]] within the [[Underworld]]. Demyx reads aloud his instructions and follows them by attacking a very confused Sora. However, he is unsuccessful and flees, leaving behind the Olympus Stone while begging "Roxas" to come back to the Organization, leaving Sora even more confused. He briefly returns to explain the nature of the [[Absent Silhouette]]s, remarking that by defeating the corresponding enemies, Roxas will "awaken" inside Sora.

Later, during the [[Battle of the 1000 Heartless]] at Hollow Bastion, Demyx returns to obstruct Sora. He greets them in a faux cheerful manner, but when Sora and his friends respond by dismissing Demyx as weak, the Nobody warns them not to judge by appearances, and he drops the façade completely when Sora remarks that Nobodies lack hearts. Although he attacks the "traitor" with all his strength, he is defeated in the end and fatally wounded. As he laments his loss, he fades into darkness.

{{canon|Instead of being sent to [[Hollow Bastion]], Demyx is instructed to track down [[Kairi]] after she escapes the [[Soundless Prison]]. He locates her and pleads with her to return to her cell for his own sake, and she complies out of pity.

Demyx is unable to stay focused when Sora later infiltrates the castle, and in fondness for Roxas, feebly protests against Saïx's orders to execute Sora and his friends. Exasperated, Saïx gives him permission to do as he wishes—so he goes to hide in the castle's kitchen, where Sora's group runs into him anyway. Sora's complete disdain for Demyx and the Organization manages to infuriate him, and he attacks with a torrent of water—which Donald simply freezes, causing it to crush Demyx, extinguishing him.||''Kingdom Hearts II'' manga}}

Demyx was "sweet-talked" by Xigbar into becoming a Nobody again to be part of new Organization. However,despite being given a fragment of Master Xehanort's heart, Demyx was informed he was solely meant as a backup member in case one of the "chosen" proved useless or were removed from the board.

Following [[Larxene]] confirming two of the [[New Seven Hearts]] are in [[Arendelle]], Demyx meets with Luxord, [[Marluxia]], and [[Larxene]] in the Keyblade Graveyard, where he complains about having been benched. Xemnas arrives to inform the four that they were specifically recruited due to their ties to the time before the original [[Keyblade War]].

Later, Vexen tracks Demyx down at [[Radiant Garden]] and tries to convince him to assist in subverting the Organization's plans, in order to atone for their prior misdeeds as Nobodies. Demyx counters that he and Vexen had no prior relationship, but Vexen explains that this is why Demyx is perfect for the role and that this is in fact [[Saïx]]'s plan.

Pursuant to their plans, Demyx later delivers one of Vexen's replicas and [[Ansem the Wise]], who Vexen had rescued, to [[Ienzo]]. Ansem and Ienzo then use this replica as a vessel for [[Roxas]]'s digital memories.

Due to his laid-back personality, Demyx is on good terms with both [[Axel]] and Xigbar, calling Xigbar "Xiggy", and often converses with him in the Grey Area. Although Axel and Roxas talk about him behind his back, Axel defends him after Roxas comments that Demyx doesn't do anything, stating that Demyx specializes in recon.  

Demyx is portrayed as being weak, cowardly, and lazy, but proves to be no pushover in the battle with Sora. He can be a formidable foe due to his ability to summon water clones that must be defeated within a time limit. Demyx, being a musician, uses music to control the water around him and to summon "water forms", objects shaped out of water into musical notes 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. Demyx 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 is most often used to play his music instead. Demyx does use one move using his sitar as a weapon, but it does little damage to Sora. Demyx does little fighting by himself, instead of relying on his control of water to make it fight for him.

*{{w|Collective Brands|Airwalk}} produces a shoe model named Demyx (one likely focused towards women with its design), and another named Roxas.
