Saïx

Saïx, the Luna Diviner (月に舞う魔人 Tsuki ni Mau Majin, lit. "Demoniac Dancing in the Moon"), is the Nobody of Isa. He was Number VII in Organization XIII and is one of the Thirteen Seekers of Darkness. He draws his power from the moon, and he uses lunar energy to enter a berserk rage in which he mercilessly attacks opponents with his massive Claymore, the Lunatic. Saïx commands the Berserker Nobodies and is playable in Mission Mode in Kingdom Hearts 358/2 Days.

Opening
No. VII SAÏX

Second in command who longs for the heart he does not have. Only the moon breaks his icy calm.

Weapon: Claymore

Enemy File
''The Organization's No. VII. Usually cool and calm, he turns into a berserker when he grips his giant blade in combat.''

''Dodge his attacks as you watch for a rare opening. After taking damage, he will revert to his normal self, making him more susceptible to attack. Finish him quickly.''

''A member of Organization XIII. As Xemnas's right-hand man, he is charged with giving orders to other members. He and Axel, an old acquaintance, are plotting something.''

First Entry
Organization XIII's Number VII.

''Nobodies like him may look like they respond emotionally, but this is, in fact, a ruse. Nobodies have no hearts.''

Second Entry
Organization XIII's Number VII.

He was in pursuit of the renegade Axel, but for some reason seemed more concerned about Sora's well-being.

''Saïx has no heart, but knows all too well how to injure one. No doubt his poise belies a more savage nature. He also insinuated he knew something about Riku.''

Third Entry
Organization XIII's Number VII.

''Saïx relentlessly chased the renegade Axel. It was also he who caught Kairi after she eluded Axel, and threw her into the castle dungeon.''

If Saïx sees something he can use, he will—and without a second thought.

''He expired after an epic clash with Sora. In his human years, he was named Isa and was Lea's close friend.''
