Reborn as a sister of a villain with no blood or tears in a war-fiction novel. Anyway, that guy, who plays ‘my brother’ role, is a villain who will be sealed by the Main Lead after losing the war. So I just need to pretend to be his little sister until he disappears. No, at least that’s how I think … ‘Something in your right hand, is that the main lead’s head?’ My brother won the war. *** “What’s with the suitcase?” “Yes?” At the tip of Dietrich’s long finger, there was a package that I had wrapped up as soon as he left for the battlefield. “I asked what it is.” “It’s, It’s a travel bag, brother.” “Travel? Alone?” Dietrich’s dark eyes glistened. The man who had just returned from victory had a strange smell of blood from mu*der. “Will you leave me?”

The God of this world had grown angry and frustrated yet again.

His world was supposed to entertain him!

It was supposed to be fun to watch!

Yet, every single guy in his world only practiced Magic all of the time!

This was so boring!

"Alright, that's it. I need someone else, someone who actually has some originality to show my world that there's more than just Magic. I need someone that is willing to destroy themselves and others on his path to power. I need someone that doesn't crack under any mortal danger."

"I should check out that other planet. Yes, you!"
