&#x3C;p&#x3E;&#x201C;In times where humans were plagued by stronger and monstrous creatures born from a malicious virus, they began to adapt in order to survive. The &#x201C;Trigger Drive Phenomena&#x22; was created which allowed humankind to fight back, the trigger drives granted humans the ability to unleash the power of their potential by connecting their soul and heart to fight as one. Thanks to this phenomenon humans are able to contend with the Infected but due to the fact that the heart and soul is connected if one&#x2019;s heart is destroyed so is their soul resulting in them either becoming a Soulless or worse erased. Despite the efforts of the Neo Spectra Organization, it did not save them as humanity would eventually be destroyed leaving one Soulless to tell the tale of how his world came to an end.&#x201D;&#x3C;/p&#x3E;
