Tatsuya is a knight who was assigned to seek help for a kingdom that was on the verge of destruction because the king lost his mind due to the death of the queen

The king intends to resurrect the queen with dark magic but the condition is 1000 lives that must be absorbed by the magic power and Tatsuya must find a "BOOK GUARD" to fight the king with great magic power

Now he wanders in the dark forest

"Where is the book keeper?"

Tatsuya's voice sounded deep and tired
