The Servant of Tsubaki Kuruoka. Differing from those called Heroic Spirits, he is only one in name. Far from a "hero", he cannot even be called a Villainous Spirit or Demonic Spirit. Some regions have called him a "curse". Called a horseman who has brought calamity to all, he is that which "let loose" the Black Death that killed thirty million people and came "under the name" of Spanish Influenza that killed fifty million people. Given a physical presence despite not being a Heroic Spirit, he continues to exist in that moment to take the lives of those on the planet to provide himself nourishment for life to begin anew.
