My autobiography is definitely not a tragedy! - Chapter 7 - 6: Estimating a Price

It began with an accident, or maybe a miracle is a better term. Three souls dying by different strokes. One died in glory and blood; One died, betrayed but glad it was over; One died poor and alone. Then on the child’s fifth birthday, the three sleeping souls awakened. Three souls, one body, two desires, and containing all the powers each had in their last life. Were they destined for greatness? No. But when the past comes to haunt them, their home taken away, they have to make a decision… May it be as simple as a majority vote.“Let’s squash them!”“...can we just run away?“Were you never taught to aim for the eyes?”

While the demons were rising, mankind was about to become extinct. Six temples rose and protected the last territory of mankind.

A young boy joins the temple as a knight to save his mother. During his journey full of miracles and tricks in the world where temples and demons are antagonistic to each other, will he be able to ascend to the strongest knight and inherit the sealed divine throne?
