The Soul Society, described as a paradise by some, are the ruling force in the Afterlife. Souls live there until they are reincarnated into the Human World. Governed by the Thirteen Court Guard Squads, and they by the Head Captain, it is as close as one could get to such a thing. However, even with such a powerful force guarding it, it is not without it's share of enemies...
Hueco Mundo, a barren wasteland populated by Hollow and Arrancar, is the Seiretei's antithesis. Yet, it is also it's main reason for existence. The Shinigami of the Seiretei are tasked with protecting the World of the Living from the ravenous predators from Hueco Mundo, putting the two eternally at odds. An exceptionally powerful Arrancar known as Colin currently leads his own personal army, much like the Thirteen Court Guard Squads, called the Espada.
The greatest threat, despite the fighting amongst the two, is arguably an anomaly only recently discovered to have a pattern. Every few hundred years something strange happens, a odd occurrence that usually follows a particularly nasty war, now what exactly happens is still unknown to this day but it always involves Hell. The gates of Hell will sometimes force themselves open and Sinners will walk the Earth once more. The cause seems to have something to do with massive conflict, or at least that is the closest guess anyone can muster, as they always open right after a large scale war, copious amounts of blood having been spilled as a result.
Much research has gone into figuring out what exactly is the cause and the best way to handle it when it happens again, but the situation is often too short lived to gain any real data on the matter. The Seiretei, being those charged with the handling of such matters, usually make sure the gates are not open long enough for there to be any real damage. The last time the gates had opened was during the Great Quincy Extermination two hundred years ago, and the results had been devastating. That had been the most powerful and long lasting occurrence there had ever been, until now...
Not only is it stronger, but something deep within the bowels of Hell has awoken, something, far more powerful than anyone has ever faced; these magnificent beings are The Sins, the same Sins which had been imprisoned in Hell for countless years, and now they have woken from their slumber and are set on making everything their own personal Hell. The Living World, Soul Society, and Hueco Mundo are all the targets of their assault, and they plan to rule over all and make everyone suffer.
However, the Seven Deadly Sins are not without their own opposite force. A group of Quincies, Humans, and Fullbringers banded together and formed the Concecro, an organization whose only goal is the complete eradication of the Sins. Lead by a being known only by Micans Nitore to most, they are the Human World's trump card in this incredibly heated battle. The Seven Obelisks mirror the Sins only in power, as their values are all but a complete change.
Hell's Gates have been opened, and the power to set in motion the apocalypse has been released! Can the Sins be stopped, or is this the End of the World as we know it?
Battle now rages on the outskirts of Seireitei as the Gotei 13 seeks to repel the invading Espada forces. The Espada are facing heavy resistance, but there is no backing down now. Unfortunately, the Shinigami are not the only ones faced with a powerful and relentless enemy. On Earth, the Sins have finally made contact with the Consecro – leaving the Vatican in shambles and the Consecro reeling. Knowing that this is only the first strike of what is sure to be a bloody and lengthy war, Micans Nitore Ania Charis has issued an order to her subordinates: travel the world in search of spiritually aware humans who can become the soldiers the Consecro desperately needs – and bring them back in one piece by any means necessary. Those who seek to prevent this conscription are to be dealt with accordingly.
