Colonial Era! Watch Me Fight for the Lives of Billions of Human Beings

The population is exploding, resources are depleting, and the door to another world has arrived on Blue Star. It is a crisis and a hope. The scum of another world drive mana battleships and wield giant swords and staffs. They want to nourish themselves with the flesh and blood of Blue Star. At this time of great calamity, all human beings work together to fight against the alien world. The horn of counterattack has sounded, we wave our swords, we drink and donate blood. All this has nothing to do with good or evil, but only a glimmer of hope. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
