IRON LEDGEROPPONENT CASE FILE
Royd Lloyd fought Kenpachi and Yamamoto from chapter 505 to chapter 509. Chapter 505 (episode 371): Kenpachi lost to Royd Lloyd. Chapter 509 (episode 372): Yamamoto beat Royd Lloyd.
Kenpachi attacks Royd Lloyd in Yhwach's guise but is severely battered and held aloft unconscious by the throat until Yamamoto descends to intervene.
Kenpachi suffers a loss against Royd Lloyd in Yhwach's form before Yamamoto's intervention rescues him.
Yamamoto fights Royd Lloyd, who has copied Yhwach's appearance and memories with The Yourself, and ends it with Zanka no Tachi's Tenchi Kaijin, which obliterates Royd's torso and arm.
Royd is the opponent in his own right and the Yhwach disguise goes in the summary, not the opponent field; the result lands in Ch. 509, and the unmasking and Yhwach's killing of Royd in Ch. 510 are aftermath.
