“Who… are you?” After the third Conference of the Seven Kings, convened following the end of the incident with ISS setups, Black Snow White and Nega Nebulas decide to end the White Queen, White Cosmos, and her legion of Oscillatori Univers once and for all.
However, before they can challenge the White Legion, they must fulfill one condition. Since the territories of Nega Nebulas and the White Legion do not border on each other, according to the rules of Brain Burst, they cannot attack that territory. To overcome this difficulty, Black Snow White proposes a secret plan—ceasefire and an alliance with the Great Wall Green Legion.
Haruyuki and the others are sent into the Sibya zone, right to the heart of the Green, to meet the Green King, Green Grande, and his officers—the Six Bastions. But just before their meeting begins, an unexpected person appears. And this burst linker with deep ties in both legions offers the Kings an incredible plan…
At the same time, the Red Queen Scarlet Rain decides to act on her own, thinking about the future of the Red Legion and all of the Accelerated World! And could we finally see the level of “Cosmos”?! The long-awaited continuation!
