How Demyx joined the Tourney

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 found by an unknown member and became the ninth member of Organization XIII.

Demyx is present when Xion joins the Organization. Axel and Roxas often tease Demyx behind his back whilst 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. This causes Xigbar to interpret his plan as voluntary and forces this plan upon Demyx instead, despite his plea that they have the "wrong guy" before being lectured by Xaldin for acting as though he has true emotions.

On Xigbar's suggestion, he is sent to the Olympus Coliseum in order to find Sora and "liberate his true disposition", either to keep Sora on 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, saying "Run, run away!", passing by Sora and company, and leaving them puzzled at his outburst. Later, Demyx steals the Olympus Stone, and encounters Sora, Goofy, and Donald within the Underworld once more. Although Sora doesn't understand the meaning of Demyx's objectives nor why Demyx calls him Roxas, Demyx took the next ordered step, which is to attack Sora. However, he is unsuccessful in defeating him and escapes, leaving behind the Olympus Stone. Before Demyx takes his leave, though, he begs "Roxas" to come back to the Organization, leaving Sora even more confused. He briefly returns to explain the nature of the Absent Silhouettes, 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, despite greeting him in a rather friendly manner. Although Sora and his friends respond by dismissing Demyx as a threat, the Nobody warns them not to judge by appearances, and his carefree air vanishes 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.

Years after, Demyx is restored unexpectedly by Zaheer. Demyx is ordered to convert the Air Nomads to Nobodies, and soon spots a young airbending boy named Meelo.
