The Boss Is Actually Me

Abnormal version:

As the original author, what should I do when one day I discover that I’ve become the biological older brother of one of the women in my male protagonist’s harem?

With the disaster looming over this world ahead of me,

and the original male protagonist bearing ill intentions behind me,

what can I do?

Looks like I can only get stronger.

After all, a sister-obsessed guy who knows the script is terrifying when pushed too far!

Even more abnormal version:

This book is also known as “For My Sister, I Might Just Take Down the Chosen One”

This world was destroyed by insect-like monsters known as “Demons.” Humanity struggles to survive in artificial island nations, like animals kept in pens.

The chosen one who could save the world failed in his previous life.

After getting another chance, he discovers that the girl who was always overlooked in his last life has somehow gained a cheat ability.

And her pretty-boy brother, who was supposed to have died three years ago,

has somehow become a threat to his position as the chosen one.
