Sirius (シリウス) is a Sin Archbishop of the Witch Cult, representing wrath.


Sirius's head is covered in disorderly wrapped bandages except for her purple eyes and her teeth. She has silver hair, covers the rest of her thin body with a black coat, and has long, distorted chains around both of her arms with ends that drag along the floor.


As shown by her position, Sirius can be scary when she becomes angry, though normally she gives off a disgusting aura. She is also Petelgeuse's stalker and is his self proclaimed wife. She speaks in an intimate, rational manner, but that attitude is off-putting. She has a distinct way of speaking, repeatedly apologizing to everyone about nothing or small things.


Authority of Wrath (憤怒の権能 Fundo no Ken'nō): Sirius is able to use the Authority of Wrath.

  • Wrath (憤怒 Fundo)
    • Sirius can share or transmit her emotions and senses to others. After polarizing emotions such as anger or sorrow, she can transmit it to any people in their vicinity, either taking control of them or resonating a certain emotion between a certain amount of people to raise it to the point of madness. Also, since she can share senses such as distress or pain, if anyone dies within the effect area she can force others within the same area to die the same way.
  • Chain Control (鎖操作 Kusari Sōsa) or Fire Control (炎操作 Honō Sōsa)
    • Sirius can control the chains wrapped around her body or transform the chains into fire and control them.


  • Sirius' name comes from the star Sirius, which is part of the Canis Major constellation and also the brightest star in the Earth's night sky
