Year 2045, alternate world. Soul Society and Hueco Mundo have been in conflict lately. Infiltrators have emerged from both sides in both worlds to cause disasters, it is not known why but it has been heard that a war could soon be started because of this.

Lucienn Krugerzmann and Rilma Grecomanto, according to rumors, are siblings or perhaps a couple, who have continued with Aizen's projects for some time since he was defeated and confined. They are the successors of the appointed one, the new leaders who have governed Las Noches and its capital for three years. Hueco Mundo has evolved and expanded for benefit, prosperity and research thanks to the two of them until forming a city. In addition, the armies of Arrancars were in good hands.

Everything is strange about this possible war because of the infiltrators even though there is a dome that protects the entire city. A rumor has it that the leaders are possibly forming this war, perhaps kidnapping Shinigamis for experiments or who knows. After all, little is known about Lucienn and Rilma's past.

All available Arrancars go to work monitoring the different areas of the city. You are outside with your friend Grimmjow standing guard, walking in the southern area of ​​the capital "Onamu" of Hueco Mundo, they are together as always, inseparable like the Moon and the Earth. Fifth and Sixth Espada side by side.
