Description
Amaterasu, also known as Amaterasu-no-Mikado or Amaterasu dis Grand Grees Eydas IV, is the immortal Emperor of Delta Belune in the Joker Star Cluster. His birth remains shrouded in mystery, marked by a delayed onset of consciousness years after delivery. He possesses an androgynous, feminine appearance with white hair and albinism, enabling a female Fatima to serve undetected as his body double.

A Physical God, Amaterasu commands potent supernatural abilities, including a formidable healing factor demonstrated during the Emperor Rescue Mission. His lifespan surpasses 800 Joker years—notable due to the shorter Joker year compared to Earth's—and extends into "Time Abyss" territory after the Traffics arc. Governed by Blue-and-Orange Morality, his judgment reflects his non-human nature.

He operates under aliases like Ladios Sopp and Mel Rince Usaretama. As Ladios Sopp, he adopts a King Incognito persona after temporarily delegating imperial duties to his Fatima double, Upandla Raymu. In this guise, he aids resistance movements and employs his engineering expertise to design most Mortar Headds (later renamed GTMs) for the AKD empire. His overarching ambition is to unite the war-torn Joker Cluster, fulfilling a Messianic prophecy over millennia through strategic alliances and extreme measures, including atrocities.

Key relationships define his reign: Dr. Chrome Ballanche, the Duke of Fates, is his lifelong friend and heterosocial partner. Lachesis, a Fatima created by Ballanche, evolves from devoted copilot to his adopted royal bride. Following her adoption into the Amaterasu line as "Amaterasu mel Gibih Lachesis Fanatic B Guires," political backlash from factions like Sarion triggers the Emperor Rescue Mission. Lachesis transcends Fatima programming to become one of his top knights.

Later narratives introduce Maximum HOLTFORS Eiz Fates Ballance XII Kaien, an artificial human linked to Ballanche's legacy, who becomes pivotal to the AKD's enduring influence. Amaterasu's legacy persists through titles like "God of Light" and his manipulation of Joker's societal structures, cementing his role as a well-intentioned extremist who reshapes the cluster's destiny.
