Seisa

Seisa (青砂, Seisa) was a Sunagakure shinobi and was the leader of Team Seisa.

Background
At some point during the Second Shinobi World War, Seisa helped repel an invading shinobi force by utilizing his Cobalt Powder, which was considered to have been instrumental in the defense of Sunagakure.

Appearance
Seisa possessed tan skin and spiky neck-length red hair and was also had large arm muscles. During the Second Shinobi World War, Seisa wore a Suna flak jacket reminiscent of the modern one but without any scroll pockets and a Suna forehead protector on his forehead. The shirt under his flak jacket possessed no sleeves and on his left arm were the stylized characters for Earth (土) and Wind (風).

Nature Transformation
Seisa's main method of combat was utilizing the Magnet Release kekkei genkai by simultaneously combining the earth and wind natures. He utilized this ability by manipulating vast quantities of Cobalt Powder, being capable of summoning vast amounts of these particles by using a special summoning technique. When used offensively, Seisa could form dozens of needles out of the Cobalt Powder and launch them at high speeds using the repelling force of magnetism or a sword that could cut clean through flesh and bone. When used defensively, he could form a large barricade of the powder. Seisa could also use the powder in more intricate ways, such as forming a large pillar to magnetically attract metallic weapons in the immediate vicinity towards it.

Trivia

 * Seisa (青砂) means blue sand. This is a reference to his Cobalt Powder that he uses as his main weapon.
