Oscillatory Universe (オシラトリ・ユニヴァース· Oshiratori Yunivaasu) is a Legion also known as the White Legion. It is led by the White King, White Cosmos. Their territory is located in the Minato area. The central base is located in an all girls' school within the area.
In Volume 18, it was revealed that the White Legion attempted to seize Shibuya from the first generation Nega Nebulus after the legion collapsed. However, before they managed to do so, Shibuya was transferred to Great Wall instead through an agreement between the Green and Black Kings, thus thwarting their plans.
In Volume 21, Shadow Lurker revealed that the Acceleration Research Society was part of Oscillatory Universe; all members in the legion knew about the Society's actions and cooperated willingly. However, only the members within the Research Circle had a BIC implanted in their brains.
In Volume 22, the connection between the White Legion and the Acceleration Research Society was brought to light at the 4th Summit of the Kings when the White King's proxy, Ivory Tower, was revealed to be Black Vise, the vice president of the Acceleration Research Society. In response, the Society attempted to attack the Kings. Having Wolfram Cerberus (now Wolfram Disaster) transport them to the Unlimited Neutral Field with Orchid Oracle's Paradigm Breakdown, Black Vise then trapped the Kings within his Third Stage Incarnate ability Icosahedral Insulation. Then, Platinum Cavalier, the first of the Seven Dwarves, dropped the Luminary-enslaved Sun God Inti onto the trapped Kings, forcing them into Unlimited Enemy Kill.

- It was mentioned by Argon Array that the White Legion has allied with/is backed by an unknown group of individuals. When the Armor of Catastrophe Mark II was prematurely born, she considered the possibility that this mysterious group had foreseen that it would happen when Cosmos failed to do so.
- According to Rose Milady, the objective of the White Legion is to bring about an end and a beginning.
- The executive group of the White Legion is described as a "demon king and their servants", with White Cosmos being the demon king and the Seven Dwarves being the servants that fight for attention.
