Toga Yagari (夜刈十牙, Yagari Tōga?) The current top ranked vampire hunter, Toga Yagari, formerly trained Zero to be a vampire hunter. He lost his right eye trying to save Zero long ago. He showed up once at Cross Academy serving for a short while as a Day Class substitute teacher, also teaching Ethics to the Night Class, and to decide whether Zero is considered dangerous or not. He appears briefly in volume five, when he appears shocked about the Council of Ancient's decision to punish Zero. He also appears in the near end of chapter 36, giving the Bloody Rose to Zero
