As I am trying to get a strand of Mom's hair, I got something more than a mere streak of keratin. Not only I acquired a special specimen of her, I also conveyed the feelings for Mom.

Although it's quite quick, the softness of her red lips remained on mine along with the samples. She reminded me that that kiss was our first and last. That moment will remain in my memory as one of my most unforgettable experience even though she's not the first woman I kissed on the lips. Sophia was my first, by the way.

Still smiling from what happened, I skipped my steps as I am walking towards our rendezvous.

"Oh. You're already here."

"Well, things run smoothly. And what's with that unsual smile on your face?"

"So you notice it, huh."

After I opened the door of the workshop, the place of our rendezvous after the samples gathered, Sister already been there with crossed arms laying her back against the milk white sofa. I immediately took notice of my weird facial expressions upon entering the fire lit room.

"Hmph. Putting that aside, have you accumulate Mom's specimen?"

"I have. And seems like you also got one from Mother."

"Anyway, here is Mother's hair."

She handed me the thing that she was holding between her slender fingers since I entered the room. I approached Sister and accepted Mother's hair then absorbed it into my right palm to analyze it.

"So you had Mother's hair, huh."

"Hmm? The way you sound it makes me think you got something more than a strand of hair."

"…I also got Mom's hair."

"Something's strange. I can feel it."

Sister's purple eyes stared suspiciously of me. It would be bad if she knew I kissed Mom. Things like beaten halfdead by Mother surfaced in my mind as I am imagining the worst case scenario. I better change the topic that could derail her thoughts.

"Can I conduct some examinations first?"

"…Go ahead."

Upon receiving her permission, I begun to carry out examinations upon our mothers' specimen. I sit down on the couch adjacent to Sister's and conduct the tests.

"First is to test our relativity."

I closed my eyes as I am examining our DNA. Just a few seconds, the result already done.

"Based on the examinations, the rate of maternity between we siblings and our parents are 100%. Means Mother and Mom is our biological parents."

"Uh huh."

I didn't doubt them a little bit. I know that they were our parents, but there was a thing that I've been wondering of. The essence of Y chromosomes in me.

Since our parents are both female, there's no pair of X chromosomes in their cells. Making it impossible to produce a male offspring, which have an X and Y. I released a sigh of relief after I saw the results of the test.

I speculated that it's because of the AlphaOmega subskill of the Ultra Skill: Monarch of the Night. AlphaOmega might change the chromosomes of an Alpha to X and Y temporarily. A magical world is really something.

"Next is our parents' genealogy."

I can track somebody's ancestry with the help of the Biological Analysis of the Unique Skill Organic Domination. But the results I found after tracing the genealogy of Mother and Mom made my eyes widened.

"What's wrong, Raphael? What did you saw?"

"Well… I discovered Mother and Mom had the same pair of great-great-grandparents. Making them third cousins."

"What they said about them being a distant relative was true after all. Them having the same amethyst-colored iris make sense now." Then fixed the same colored eyes on me. "Well, it's definitely more moral than the one in front of me who will be marrying his own full cousin."

"Why would you have to attack me personally? We genuinely love each other so there's no problem of us being related."

Sophia and I are indeed full cousins and shared the same pair of grandparents. But that doesn't stopped us from loving each other.

Besides, no matter what or where the world I am, inbreeding is a common practice in aristocracy, just to make the bloodline pure.

(You know, I'm something of an aristocrat myself.)

As if irritated by my satisfied smile, Sister broke a chagrin.

"Hmph. Enough of this chitchat. Are the samples enough for you to replicate our parents' Longevity?"

"More than enough."

<Analysis on the samples has been completed. Extra Skill: Longevity has been acquired.>

"That's good then."

With this, I can live eternally and make someone immortal by my skills despite didn't reaching the High Human realm. Now, I can make Sister owed me for real.

I stood up from where I was sitting then approached my bewildered beautiful elder sister. I filled the vacant space of my sofa like what I did in the living area earlier. Facing her, I gently stroke her left cheek with my right hand down to her chin.

"You knew that I cannot grant it for you without a proper payment, right."

"I know."

I reminded her with a persuasive, soothing voice. Sister answered as she turned her reddened face away from my sight. It's rare to see this cute side of hers.

"As for the advanced payment…"

With my fingers still on her chin, I fixed the position of her head to face mine. I fixated my eyes upon and leaned my face closer to hers.

As I looked into her eyes, several emotions clouded around her lilac gazes. Fear, disgust, resolve, anticipation? I shrunken the gap between our faces and then—

"Well… I will just pile it along with the ones that you owed me." I shifted the trajectory of my heading towards her right pinna and speak quietly upon it.

"Huh? You little…!"

Clap.

Betrayed by her own expectations, Sister gave me a dry and crispy slap on my cheek. The strong impact made me comically flew and embedded against the wall. Like that in a manga.

"Don't talk to me today!" Yelled Sister before she walked out of the room.

"Perhaps I shouldn't play a girl's feelings too much?" I asked the silent room before I fell off the wall.
