Drinking 地獄の血
When Drinking 地獄の血:

Most of this power was unknown to Karito or Crimson Knight. Only Miko was able to witness this ability Dorei was using. When Dorei drank 地獄の血, it enhanced his powers, (Even his reflexes, like Katsuko) making him feel stronger,faster, and more durable. (This is what helped him kill Miko) If Miko were to have never killed him, he would have died either way due to the aftermath of 地獄の血.
