Rubedo (ルベド) is the youngest sister of Nigredo and Albedo. She is considered to be the Strongest Entity of Nazarick.



Not much is known about Rubedo's personality, but Nigredo claimed that she's not the type that others can easily open their hearts toward.


At some point she was created by Tabula Smaragdina using a unique process that differs from other NPCs.

Albedo and Nigredo had a conversation about Rubedo. Nigredo warned that Rubedo will bring a calamity to Nazarick, but Albedo replies that she would never do that. In contrast to Nigredo, Albedo only sees Rubedo as an adorable younger sister.[1]

For the possibility that the other Supreme Beings found their way into the New World, Albedo put forth a plan to create a squad to search for them. Albedo asked Ainz permission to take command of Rubedo in her squad. At first he rejected the idea, saying that the experiment with Rubedo has been more or less a success and that he don't plan to move her for the time being. When Albedo said that she wanted to create the strongest team, Ainz bursted into laughter, because he thought it was a childish yet understandable explanation. In the end, he allowed her to use Rubedo.[2]

Abilities and Powers

Among all of the denizens of Nazarick, Rubedo is the strongest and most powerful NPC that can overwhelm Ainz Ooal Gown with full equipment, and stronger than Touch Me. Rubedo is also one of the four close combat specialist NPCs (Cocytus, Albedo, Sebas Tian) and of course, the strongest among them. Ainz expected that he should give a World Item to "Them" in the 8th Floor to beat Rubedo. However, Ainz stated that no matter how strong Rubedo is she would not be able fight one of "Them" to a draw.


Ainz Ooal Gown

As the strongest being in Nazarick, Ainz expects that he should give a World Item to “Them” in the 8th Floor to beat Rubedo in case she were to one day turn against Nazarick. Ainz commented that the experiment to start up Rubedo has been more or less a success and that he doesn't plan on moving her for now. When Albedo requested Ainz to allow Rubedo into her squad, he initially rejected, though he later changed his mind.


Rubedo is Albedo's younger sister. Unlike Nigredo who despises her, Albedo thinks Rubedo is adorable and that she would never be a scourge to Nazarick. She asked Ainz permission to get Rubedo in her squad, which he allowed.


Nigredo is Rubedo's older sister. Nigredo despises Rubedo and calls her Spinel. Although Rubedo is her younger sister, Nigredo views her as a potential threat to Nazarick, because she was not made the same way as the others. She claimed that Rubedo is definitely not the type that others can open their hearts towards.


  • In the Web Novel, Rubedo doesn't exist, along with her sisters.
  • Rubedo is a Latin word meaning "redness".
  • The name "Spinel" is the derogatory term for Rubedo by Nigredo.
  • It is very likely that the original position of Rubedo is in the 8th-floor, considering that the 8th-floor is guarded by the most powerful NPCs.
