Demyx

Demyx is number VIIII in Organization XIII. He 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. He wields a sitar (a guitar-like instrument) and uses the power of water.

Role in the Organization
Demyx's role in the Organization's plans is minor. He was sent shortly after Sora awakened from his slumber to find Sora and liberate Roxas, Sora's Nobody, from within Sora. Although Sora didn't understand the meaning of Demyx's objectives, which he read aloud in the Underworld, Demyx was unable to fulfill them and tok the next ordered step, which was to attack Sora. Demyx at first only summoned "forms" of water - water shaped into musical instruments, which then attackd Sora, Goofy and Donald - which he controlled with his sitar. He was unsuccessful in defeating Sora, however, and fled after his water forms were destroyed quickly.

Demyx confronted Sora later in Hollow Bastion during the War of 1000 Heartless, again calling Sora by the name "Roxas". When Sora didn't respond and called his efforts futile, Demyx's normal carefree aire vanished, and he attacked Sora again. Summoning more water forms to assist him using his sitar, Demyx fought using the power of water, using various magic attacks combined with rushing attacks with his sitar. In the end, however, Demyx was defeated again and fatally wounded. After lamenting his loss, he fades into darkness, the first Organization member to do so in Kingdom Hearts II.

Personality
Demyx is most easily distinguished from the other members of the Organization by his personality, which is good-humored and energetic. He seems not to take his task seriously and doesn't hesitate to read his orders aloud 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.
