Seimei

was the founder of Takumi Village. He was known for creating weapons for the other shinobi villages.

Personality
During his short appearance Seimei acted calm, cold and aloof, believing his opponents efforts to be in vain against his power, openly laughing at them, showing his arrogance and pride. It was only when his opponents managed to successfully strike back or elude his attacks that Seimei lost his cool. Seimei was also credited by Gaara as believing ninja to be nothing but weapons.

Abilities
Seimei was considered a great and powerful shinobi to the point that the villagers of Takumi considered him to be the ultimate weapon. His mastery of weapons and wind release techniques certainly testified to his power. After equipping the weaponry and armor of the Four Celestial Symbols Men, he was able to use their abilities and his wind release without any apparent movement or even hand seals. Wearing them also gave him the ability to float on a globe of chakra. Seimei also showed quick analytical and deduction skills when he merely glanced at the cage imprisoning Gaara to understand what had transpired before his resurrection.

Ultimate Weapon Arc
Hōki, Kujaku, Ryūgan, and Suiko removed his body from his crypt with the power of the Shukaku. Hōki then sacrificed his body to revive Seimei. Once the preparations were complete, Seimei used the weapons from his dead comrades to create the "ultimate body". He was later killed by Gaara. Though Seimei was difficult to kill, the fight was essentially over when he was hit by the Ultimately Hard Absolute Attack: Spear of Shukaku in his chest, demolishing the so-called "indestructible" armor. Gaara wasn't taking any chances, and followed up with a Sand Waterfall Imperial Funeral in the pit of sand he had created using minerals from bedrock making both Hōki and Seimei deceased.

Trivia

 * Seimei's name is likely taken from the legendary Japanese mystic Abe no Seimei. Strangely, the Seimei of legend was supposedly born from a Kitsune (A japanese fox spirit) while Naruto's Seimei was revived through the chakra of Shukaku, a giant tanuki.

Quotes

 * (To Gaara) "Pathetic, Shinobi have no need for emotions, those that kill their emotions become more powerful, and that power is the only justice. You're already finished."
