The Demon Prince Goes To The Academy

I died while I was reading hate comments on my novel.
I was already in shock over my death

but some 'Grim Reaper' appeared and told me that being a bad writer was a sin.

To atone and make it into heaven

I was told I needed to survive past the ending in one of my novels.

And so, I entered the novel 'The Demon King is Dead'...

"Damn it all!! Why did this have to happen to me?!"

By all misfortune, the character I possesed was the Demon Prince

a character with no combat abilities

who dies at the very start of the story!!
