Toga Yagari is currently the top ranked vampire hunter, as well as the one who trained Zero to be a vampire hunter. He lost his right eye trying to save Zero long ago. He appears at Cross Academy serving for a short while as a Night Class substitute teacher of Ethics, and to decide whether Zero is considered dangerous or not.
Yagari is shocked to learn the Council of Ancients' decision for punish Zero the death of Shizuka Hio and later appears to arrest Zero for other charges. Before leaving Zero, he gives him the Bloody Rose. Yagari subsequently joins the Chairman to protect Cross Academy from the Hunters Association.
