Final Mode: Atmospheric Rift

Final Mode: Atmospheric Rift (・渾楔颯 Fainaru Mōdo: Konketsusatsu?): Typically used as a last resort, A uses the tubes for his wind suit to gather huge amounts of air and compresses it in his lungs. The air is then released through a slit on the horn of his head, causing it to become as sharp as a razor blade. The wind flails about much like a whip and is sharp enough to cut through stone. However, due to the scraping and heat led by the quick wind compression, the technique slowly tears apart A's body until he collapses.
