Sage Art: Pandemonium of the Netherworld

While in sage mode Yoshikage summons a few ravens. They begins to sing wich unleashes energy-eating phantoms from the mouths of summoned ogres. The phantoms themselves are composed of spiritual chakra and require the consumption of physical energy to retain their stability. It appears that the phantoms are immune to physical-type attacks and can disable an opponent's ability to use chakra.
