Hihiō is a core feature of Renji Abarai's Bankai, Sōō Zabimaru, in which part of the weapon becomes a massive skeletal arm that mirrors his own. The limb hits with crushing force, snapping bones and hurling enemies through walls.
Hihiō is one of the defining traits of Sōō Zabimaru, the Bankai wielded by Renji Abarai. Its Japanese name translates to Baboon King, keeping with the primate theme of his sword. It functions as a raw power move built into the release itself.
The collar of Sōō Zabimaru reshapes itself into a large bony arm that tracks every motion of Renji's left arm. The construct carries formidable strength, able to break bones with ease and fling an opponent hard enough to send them crashing into nearby buildings.
