Hayato Kunato, twin to Kusui and older brother to Hyoma, was a prodigious combatant within the Saenome clan. By age 16, he had surpassed Zouhei Kunato in fighting ability, a fact acknowledged by both himself and others. His self-assured personality was evident in his use of the term "oresama." Hayato met his end at the hands of the tsukumogami Tenbi, specifically identified as Karakasa no Tsukumogami. This death profoundly impacted his family, significantly fueling Hyoma Kunato's deep-seated hatred of tsukumogami.
