Seiichirou Sano
Sano can change towels into iron by holding his breath, however sharp-eyed fans can see that sometimes it appears to be voice-activated instead. But after he gives the commands, he is sometimes left with a second or two to stop breathing in.
Sano, a 9th grader at Inaho Junior High School, was known as the Genius of Robert's Ten while he was part of it. But he had joined because the leader of Robert's Ten (Karlpaccho) had placed a Death Pentagon on Sano's King of the Celestial World Candidate Inumaru that would kill him by removing all his blood unless he listened to Robert.
Sano can be creative with his power, creating shields, springboards (spring) and even boomerangs which he calls “boomerang cutter”.

His Level 2 makes his steel towels into powerful magnets. Seems to possess a ridiculous amount of his necessary towels, pulling them out of his robe in rapid succession. He even has an emergency towel tied around his forehead.
