Yoroi Akadō

is a member of Kabuto's Genin Team.

Chunin Exams arc
Yoroi and the rest of his team enter the Chunin Exams to spy on their fellow participants for Orochimaru. During the preliminaries he is matched against Sasuke. Yoroi used the Chakra Absorption Technique against him, making it very difficult for Sasuke to keep his cursed seal under control. Despite this, Sasuke defeated Yoroi with taijutsu, finishing him off with his newly devised Lion Combo.

Land of the Sea arc
Though Misumi and Yoroi are not seen again in the manga, they appear in the anime's Land of the Sea arc. They are research assistants and bodyguards to Orochimaru's former scientist, Amachi. He, like Misumi, has taken off the cloth covering his lower face and he wears a completely different wardrobe. During the events of this arc he fights Shino Aburame twice. He is ultimately defeated and sinks beneath the water after a final attack by Shino's bugs. His status remains unknown, though it's highly unlikely that he drowned.

Abilities
Yoroi is a competent ninja and his most notable technique is the Chakra Absorption Technique with which he can absorb the physical and spiritual energy of an opponent on contact. This extra chakra can be used to perform techniques that drain a lot of Yoroi's chakra. In the anime, he shows a better assortment of techniques: Demonic Illusion: Descending Hell Technique, which creates a ball of fire in the sky. He is also shown proficiency in water-chakra from creating Water Clones and is also seen using Water Release: Huge Explosion Technique to try and capture Shino.
