Keeping the peace of the world is the priority of humanity. Lumen Umbras, a private globally funded task force exists for this very reason in many fields that involve the security and advancement of humanity. However, what they have yet to realize is that their influence on protecting humanity makes those who wish to tear humanity apart. Those with power, those with a twisted vision, who seek opportunity to change the world - these are the people that Lumen Umbras deal with. The upcoming generation of heroes about to carry on the torch are no different from any other generation before them. Well, except that they have the hardest batch of adversaries in human history.
