The Demon God Awakens: The End

The Demon God, whose soul was shattered long ago, has now returned. Will humanity be wiped out, or will it fight to the bitter end?

What kind of story will unfold for a student who possesses fragments of the Demon God's soul?

All will be revealed in this book.

(The backstory for this book is "Skad Technology," which you can read on the 17k website. The story is even better when experienced alongside the backstory.)
