Info on the story

The Great Tenma War...

An event that happens every 500 years. Angels rain down from the sky, causing destruction on humanities strongholds that have developed too much.

The event works pretty simply, if the humans win they live another day and if the angels win then all humans go extinct.

The stakes are high in such an event, no one is safe during this event. Especially not after what is assisting the invasion...

The Greatest Tenma War ever, primordial angels alongside insectars, phantoms and many more that even put demon lord's to shame.

Let's see how our protagonists fare, shall we?
