Gekitotsu no Hexennacht - Volume 4, Chapter 9: An Incompletely Seen Place

I reincarnated as the villain’s younger sister who will be punished by the male lead. It was a forgone conclusion that both of us will die to the male lead if my older brother continued his evil ways. So I tried to live quietly while trying to change my wicked brother, but for some reason the male lead is lying in front of our villa? I can’t let him die, so at first I helped him up, but…the male lead’s condition is a bit strange.

Wait a minute…did it start already? The male lead’s mana poisoning? There is only one way to calm the enormous amount of mana within the male lead’s body. Immediate physical contact…

But that’s the female lead’s job!

Aren’t I the villain’s sister? Why me?! What the hell is going on?!

“Rose…Please, I need you. Save me…”

This is driving me crazy…I can’t turn a blind eye to the dying male lead, and there’s not enough time to find the female lead!

…Gosh, I don’t know!

Let’s save the male lead first! I’ll help him, then once I find the female lead, we’ll break up! I quietly approached him and we kissed. But as if that alone was not enough, with a deep sigh, he spoke.

“Let’s have a deeper relationship.”

“Deeper…relationship?”

“Kissing, and other things…”

He looked at me sorrowfully. I couldn’t take my eyes off this great beauty when he looked at me in such a somber way. Absentmindedly blinking my eyes, I inadvertently nodded my head. Then he pulled me in and locked his arms. With a dazzling gaze and a bright smile, he spoke.

“Rose, you’re my first.”

No, I can’t be your first time!

In a tyrannical world, what is evil? What is benevolence? All living creatures are brutal. Passing through the heaven road to find one’s purpose in life. Struggles to be stronger is not an easy path. The whole journey thistles and thorns, one blade chops open a path, I alone will be supreme!
