Our world changed beyond recognition when a horde of demons from another dimension invaded Earth. Guns and missiles were powerless against the crushing combat magic. Armies are defeated, state capitals are reduced to ruins, humanity is almost exterminated. But among the ruins, representatives of the new generation continue to hide, those who grew up after the invasion and cannot imagine life without constant struggle with the invaders. Capable of facing the most merciless enemy - and not retreating in fear. Masterfully wielding bladed weapons and firearms, practicing martial arts and mastering enemy magic. Fearless fighters, the only and last hope of humanity.
