Ultimate-Class Devil (Formerly)
2nd Ranker (Formerly)
Belphegor Head (Formerly)
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, cherry-blossom coloured hair and two horns protruding from her head. She wears a seductive dress with high slits.
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 bored.
She is said to love young human males in their teens to their twenties, as seen when she placed her hand under Issei's chin, flirts with him and calls him "Cute".
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 (unknown to everyone that 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.

In Volume 23, she reappeared through a magic circle at the training area underneath the Gremory castle, where Ravel informed Issei that Roygun has become their advisor. She has been put under surveillance for her involvement with the Rating Game scandal due to using a King piece. She handed a pile of documents regarding Rudiger Rosenkreutz who is Dulio Gesualdo's coach and starts taking a interest in Issei, flirting with him. She appeared before Issei again at the Hyoudou Residence and pledges herself and her servants under Issei as his servants and joins his team for the Rating Game World Tournament.
