Yubelluna is Riser Phenex's Queen and the strongest member of his peerage. She is also known as the Bomb Queen. [1]


Yubelluna is a voluptuous woman with long, wavy purple hair that falls all the way down her back and matching eyes. At the front, the right side of her hair falls over her breast and covers her right eye, while the left side falls near the top of her skirt.

Her attire is a dress consisting of a navy blue tunic top with gold accents and a pale blue skirt with open sides, black shoes and over matching thigh-high stockings with garter belts. The top reveals much of her cleavage, and is held with a gold choker with blue and red jewels. Over this, she wears a white overcoat with black and gold accents and matching pauldrons. For accessories, she wears a black headband with a red-orange jewel over her forehead to keep her long hair in place, and wields a staff-like scepter in battle. For cosmetics, she wears purple lipstick and nail polish, matching her eyes and hair[2].


In combat, Yubelluna is a cunning opponent but extremely submissive in Riser's presence.[1]


Not much is revealed about her past, only that at one point in time, she was reincarnated as a Devil by Riser.


The Red Dragon Emperor's AwakeningEdit

Yubelluna was introduced in Volume 2 when the Occult Research Club members met with Riser and his peerage. At the Rating Game match between Riser and Rias Gremory, she was sent to the front lines by Riser after Issei Hyoudou, Koneko Toujou and Akeno Himejima defeated Xuelan, Mira, and Ile and Nel, where she defeated Koneko while Koneko and Issei were careless. She then fought against Akeno in a one-on-one fight and won (albeit with the use of Phoenix Tears). Yubelluna then defeated Yuuto Kiba after Yuuto and Issei successfully defeated all of Riser's remaining peerage members with the combining of the Sword Birth enhanced by the power of Boosted Gear Gift, except for Ravel Phenex, leaving Rias with Issei and Asia Argento, before heading back to her master's side. When Issei appeared during Rias and Riser's fight, Yubelluna offered to take on Issei and Asia but was stopped by Riser, who wanted to clear things up and finish the battle.

The Legend of Oppai Dragon and his Lively CompanionsEdit

In the Extra Life of DX.1, Yubelluna took part in her master's rematch against Rias. She faces off against Akeno who held a grudge towards Yubelluna for defeating her last time, as Akeno fights her with the full extent of her Fallen Angel Holy Lightning abilities. Later on, she is retired for losing her match with Akeno.

In Volume 19, Yubelluna participated in the Rating Game between their master and Diehauser Belial.
