[Blood Eclipse Release] Ultra Recovery Kyoya's blood has the effect of multiplying an Oni's recovery power many times over. Even for those who have lost limbs, hands or feet can be regenerated with a large blood transfusion. However, there is a drawback: if a large amount of blood is ingested, antibodies are formed, and the patient's body cannot handle further blood. Therefore, if limbs are lost, one must choose whether to regenerate a hand or a foot. He can also heal himself by bathing in his own blood, a fact he discovered during the Kyoto arc when his carotid artery was cut by Tsubakiri and he accidentally drank his own blood. Incidentally, during his time at Rasetsu Academy, it took 7 minutes to heal a leg injury.
