Beelzebub, Ajuka
Summary
Ajuka Beelzebub, formerly Ajuka Astaroth, stands as the supreme leader of the Underworld and the sole remaining Satan following the conclusion of the Evil Dragon War. As a Pure-Blooded Devil, he holds the title of Super Devil, a rank shared only with Sirzechs and Rizevim, whose power surpasses that of the original Four Great Satans and rivals certain deities. His immense strength allows him to effortlessly defeat Old Satan Faction members, including High-Class and Ultimate-Class Devils, while remaining seated. Zeoticus noted that their power was so vast that only the position of Satan was fitting for them. Beyond his combat prowess, Ajuka serves as the Chief Adviser of Technology and is the architect of the Evil Pieces system and the Rating Game. He was formerly the heir to the Astaroth Clan and led the Three Factions in the Underworld before becoming the founder of the Rating Game and organizer of the Azazel Cup. Ajuka’s demonic power is unique among Devils, specializing in creation through calculations. He developed the Kankara Formula, or Equation of Military Supremacy, which allows him to control phenomena using equations. This ability lets him manipulate enemy attacks, altering their shape, direction, and power. He is also a master magician with a genius intellect that rivals even Azazel’s. In his youth, he devised anti-spells against the Jabberwocky and Bandersnatch during the events of Volume 12. His tactical brilliance, alongside Falbium, enables him to predict future events, earning him fear across other mythologies. As a scientist, he is a multi-talented genius in mathematics, physics, and demonic technology. He created the Evil Pieces System using the Original Satans’ ancient Agreas technology and is the only one who knows how to create the forbidden King Piece. His scientific genius extends to invention, where he modified Evil Pieces to allow Issei to promote without permission and created Mutation Pieces. As a politician, he works with Sirzechs and Serafall to govern the Devils while maintaining relations with the traditionalist Great King Faction. He can fly using his Devil wings. Ajuka has created several significant inventions, including the Evil Pieces Scanner, which detects abnormalities in pieces, as seen when the Occult Research Club visited him. He also reclaimed the rare King Pieces, originally created in the early days of the Rating Game but discontinued due to misuse risks. These pieces were initially snatched by the Old Devils, but Ajuka recovered them after Diehauser Belial exposed their existence.
