Roygun Belphegor is the former Head of the Belphegor Clan, the former second ranker of the Rating Games and a former Ultimate-class Devil. She reached the top of the Rating Games through her King Piece before being stripped of her rank and all her titles for cheating in the Rating Game due to it. Roygun was also shunned from her household.
Roygun is a beautiful young woman appearing in her twenties with long, wavy, pink colored hair and two horns protruding from her head. She wears a high-cut formal dress with high slits and has a well-endowed bust and slim waist.
After becoming a temporary nurse of Kuoh Academy, she wore a white gown and a miniskirt that showed her legs and wears glasses.
Roygun appeared to be a kind and noble woman. Unlike Bedeze, she didn’t have a rebellious side as she tried to stop Bedeze from attacking the Bael clan and take down those who used the King Piece. Roygun became remorseful after she helped the Rating Game’s corruption come into play, yet despite this she didn’t have regrets as she wanted to use the King Piece for fun. Roygun is said to love younger males from their teens to their twenties, as seen when she openly flirted with Issei for having a cute face in front of the female members of his team.
Roygun holds a great deal of love for the Rating Games, even though she used a King Piece to obtain power. Her love for the games were shown when she pledged herself and her servants in front of Issei to be his retainers, to be able to participate in the Azazel Cup, as she can't let go of the Rating Games which she loves so much. She has a pretty laid back personality as even though she was shunned from her household, it just caused her to become inconveniently depressed.
Roygun is shown to be very wise and intelligent as she was able to gain information on Sacred Gears even before Heaven and Grigori makes an announcement on them, something that surprises her team leader Issei.
Sometime before the series, Roygun became the Head of the House of Belphegor. At some point, she became the second champion of the Rating Game (unbeknownst to everyone, she was using the King Piece to win).
Roygun was mentioned in Volume 10 as the second ranked champion of the Rating Game in the Top-10.
She first appears in Volume 21 in an attempt to stop Bedeze Abaddon from pushing the corruption of the Rating Game towards the Bael Clan, but arrived too late as Sairaorg had already beaten him. She then brings Bedeze to the guards instead.
