Magnet Release: Iron From Blood

The most powerful technique in Sakino Taka's arsenal, the Magnet Release: Iron From Blood is a suicidal technique taught in Kumogakure to be used as a last resort for the Magnet Release users.

Overview
The user bites his wrists, sending Magnet Release chakra inside his bloodstream. The iron from the blood then becomes magnetized, turning the user into a veritable "shrapnel bomb" that explodes, spreading small bits of iron with incredible speed towards any direction. The jutsu is lethal for the user and those caught in the range.

History
Sakino Taka told the story about the fact that Toroi, the greatest Magnet Release user of Kumogakure killed 137 Iwagakure shinobi after they cornered him during the Third Shinobi World War.
