Aizen had unleashed a power that this world had not seen the likes of. Two planes of existence had been separated through time to keep their energies from mixing. Through Aizen's research and knowledge, he had tried to take this power of both for his own using the young Heiress to the Hellgate name. Unbeknown to him, her innate abilities steeped in her blood and lineage had mixed with the powers of the other world, the key reason the worlds were separate in the first place. The two were not to be mixed.
This released a passive shockwave from one world into the next, spilling the energies of each into the other at certain points. On their side, Nagase was the energy incarnate. On this one, a flood of pure Alter energy permeated the whole of the Kingdom of Chaos. It filled every inch of the Kingdom thick with its heavy influence, but it would go unnoticeable to those without an acute sense of perception. There is no change but the immense presence of a new energy. One so elusive that it has the power to Alter how matter interacts in this world. Nagase had been the conduit for change, but for every wrong purpose. Aizen was closer to his goal. The Kingsom of Chaos seemed to be the worst casualty. Its whole existence was Altered.
