^Ayato has only a Ukaku. He can manipulate it in a way that his Ukaku is like a Koukaku and doesn't strain his stamina that much. Many ppl suggest that he can manipulate it in that way cause his father was a Koukaku. So maybe the mother DNA was more dominant than the fathers, like maybe 70% to 30%.
