The Imperial Academy¹
Greatest School in "The Empire" on continent of West
One day creatures called "Demons" began to massacre living creatures and occupied lands for decades.
The previous dominant species called "Humans" retreated to underground trying to survive with little resources they had.
With that the hierarchical structure built over the entire history of humanity fell apart piece by piece.....
People with powers enough to hurt demons were born after a decade of dominance and they we're called "Defenders" by the people.
Defenders had came as a ray of hope for people who had been treated badly by demons but there was those who defended the demons and fought for them as pawns and foot soldiers.
Fortunately for me, Ethera I was born and raised in the demon territory that raised the strategists for the war.
When Ethera was 12 years old boy Ethera had been treated as a burden but after Ethera grew up to be adult Ethera was in the top 10.000 and slowly but surely began to be valued and changed the treatment of other humans by demons.
Ethera had realized that I were the most naive guy in the army after getting abondened and betrayed by the very people I had helped without me as I closed my eyes ready for execution for being a deserter I heard a stern and commanding voice telling me to not give up resisting I heard horses galloping towards the place I was at
It was my own unit of armed Demons-Humans squad
"Captain you can't abonden us"
"yeah captain if you do we will follow you even in hell!"
"For the Capt!"
As the two sides began fighting my side had gotten surrounded by the enemy side but they had saved me I muttered "idiots..." and we prepared to put a last fight against the demons we had betrayed.
Ethera had won the battle but he had lost a lot of friends only my aide was standing in my arms alive but heavily injured I had lost everything...
As he was closing his eyes Ethera heard a voice
"Do you wish to be reborn"
"Y-Yes"
When Ethera had closed his eyes he had been reborn as a teenager with injuries everywhere on his body.....
