Various unnamed children

One of the main antagonists of the series, Kiryu is considered as the incarnation of the devil by anyone who has met him. He is more of an anti-hero type as he constantly pushes Kibo to surpass his limits.

Personality Edit

Unlike his brother, Kiryu is wicked and completely ruthless. He is also an intellectual that quotes philosophers, appreciates art, and read many books even when hospitalized. But this is only another facet of his ruthless nature, because Kiryu values mental and physical strength above all else.

Appearance Edit

Kiryu looks almost exactly like his brother Seiko, since they are identical twins. The only exception being that Kiryu has slicked back hair, a scar across his face and he doesn't wear glasses.

History Edit

Abilities Edit

  • Superhuman Endurance- Kiryu has been able to fight on with gouged eyes, a crushed throat and broken arm.


  • In the side story Tankōbon "Oton", it is revealed that Kiryu fathered a child with the daughter of the United States President.
  • Kiryu can play the piano.
