[A/N : I've finally finished setting the auxiliary chapters.
I'll upload those chapters containing the characters information, notes, and other important information about the world: about magic and special abilities, continents, Paths of Gods, and including some slight spoilers for the next volume, at the end of this volume.]
How long has it been since we've started...?
"Ah~! Ah~! Ah~!"
...An hour, maybe?
"Hnnn~!!"
While I was pounding Otuko from behind, I couldn't help but sigh deeply in contempt. Looking at her bare back, I thought for a bit.
Otuko, she's... A bit...
No... She's a real masochist.
I confirmed this when she wet the bed. Doing the rough method after letting her humiliate herself, then... Sure.
She didn't even tried to deny it.
[The conditions have been met!]
"...?"
I came to an abrupt stop the moment I saw something appeared in front of my face, catching me by surprise.
[You have successfully obtained "Replace"]
This...? Isn't this one of her ability?
My mouth opened up and closed, speechless from what I'm seeing. It was the ability she used to teleport the Boss to the sky... How did I even get this?
...Conditions? Does having sex with someone let me get some of their skills?
"...Interesting."
Shaking my head lightly, I reached out to her wrist and pulled her up. Following this, I pulled my "dino" out, then forcefully pushed it back in.
"Haannnn~~?!!"
Otuko moaned loudly with her tongue stuck out. Her expression look erotic; her tears and saliva was visibly pouring out, and her eyes had already turned white. Her brain must've been fried by pleasure and pain, considering that she already look like she couldn't think anymore.
Ahh... I want to see more of these.
"Heh..."
What happens when a person breaks out of their character...? I've always wondered about this question myself.
"Why don't you call me master?"
"Nnn...huh?"
Erm... I think I'm asking her something a bit unreaso—
".....Ma—Master...."
"...."
Or maybe not...
"Ugh..." I groaned when I felt her insides tightening up.
Shit...
Otuko glanced at me from the side of her view and said, "Please.... Ah... Mess me up more~!"
I suddenly felt the strange urges inside me coming back.
"It's—ah~! Getting bigger inside!"
...This might take long.

Somewhere within the vast expanse of the mansion.
"What's your take on this place?" Solis, donned in an adorable set of white pajamas, inquired of Odium, who lounged beside her, engrossed in a novel.
Odium shifted her gaze towards Solis, offering a hesitant nod that conveyed her contentment with a subdued hum.
"It's good..."
Solis beamed at the acknowledgment, then shifted her focus to the slumbering girl nestled on the edge of her bed.
The same girl their Contractor had brought into their midst a mere three days ago.
"Who do you think she is?"
Solis vocalized her musings. When their Contractor presented the unconscious girl to them, he had remained cryptic about her identity, only mentioning that she was a friend's daughter.
"The noble seems to have a connection with this girl... Plus, our Contractor acts peculiarly around her."
The conclusion lingered in the air – the girl's parents likely perished during the recent events. Given their significance to the Contractor, he chose to extend his care to the orphaned child.
That must be it... There's no way our Contractor would bring a child unrelated to him in someway.
He must have felt compassion for her plight, deciding to provide a haven by adopting her... This would elucidate the Contractor's seemingly overprotective demeanor towards the little girl.
A sense of determination flickered across Solis' countenance as she pieced together the puzzle.
In the midst of contemplation, Solis observed Odium rising and making her way to the door. Puzzled, she tilted her head and inquired.
"...Where are you going?"
Odium partially turned her head in response, scratching her cheek as she replied in a subdued voice, "I'm already tired, so I'm going back to my room..."
"Ah! I see... Well, that's understandable. You should go ahead and rest. I'll keep an eye on this girl. If she regains consciousness, I'll inform the Contractor myself." Solis offered a reassuring smile, redirecting her focus to the slumbering girl.
The girl lay undisturbed on the bed, her head nestled on a pillow beneath a cozy blanket.
After a nod of acknowledgment, Odium exited the room and securely locked the door behind her, retracing her steps to her own quarters.
Having already completed her nighttime routine in Solis' room, Odium hadn't had a chance to inspect her own quarters.
Upon entering, she noted the striking resemblance between the designs of both rooms. The furnishings mirrored one another, and all the essential amenities were meticulously arranged and immaculate.
...It appears entirely pristine.
Once she secured her room, Odium proceeded to her bed and reclined. Flipping open her book, she prepared to resume reading where she had left off.
However—
-Nnn~!
A peculiar noise emanated from across the room, interrupting her concentration.
"What is that noise?"
...Is it here?
After scrutinizing the entire room, Odium deduced the source of the sound and leaned against the walls, pressing her ears to discern the mysterious noise.
—Mmmnnn~?
—Ah~!?
Odium fell back on the floor, her face becoming visibly red as she realized what was happening on the other side.
"Umm... Ah...."
Aren't they doing what lovers should do when they're alone together...? Like how a married couple make children?
...No one will notice me listening, right?
After contemplating on what she should do, Odium hesitantly leaned in again to the wall to listen.
Upon hearing their moan, Odium covered her mouth with both hands and closed her eyes to imagine what was happening.
—Ah~! It's too big...!!
"Ah...!"
—Wait, what are you—?!
Out of the sudden, the noise became louder.
—Why!? Nnnn~! Someone—nn~! On the other side—ah~! Might hear~!
Odium became red again as she hurriedly jumped back to her bed. Covering her head with the pillows, she pondered the identity of the two on the other side of the wall.
Those voices... Didn't they belong to Contractor and Otuko?
—Tell me, what am I again~?
She heard Contractor's voice.
—Ma-master! Yo-you... hmm~! Are my only master!
—You don't mind me finishing it again inside, right~!
—Y-yes...!! Please—Aahnn~! Use me as you like~!!"
—If you say so~
Out of the sudden, the pounding sound on the other side intensified. The walls began to creak more loudly as Otuko's moans began to get louder.
Soon, the pounding stopped as Otuko let out a moan that echoed her ear.
"Aaaahh~!"
...I want a sound proof wall next time, Odium thought, covering both her ears as tears began to form from the side of her eyes.

(Saber POV)
In the morning.
"Master..."
"You know, you can stop calling me that. It's already over."
"...How did you know that it was my first time, Master?"
Did she really ignore me?
While dressing, I turned to the right, examining my reflection in the mirror. The visible bite mark on my neck caught my attention, prompting a heavy sigh of disdain.
Without directing my gaze toward her, I spoke nonchalantly, "I heard you mention that you often watch anime, right?"
"...yes?"
"That should answer your question on how I found out you're single and a virgin."
Lying on the bed, Otuko weakly attempted to reach out and punch my left hip, but her effort was feeble and went unnoticed.
"...𝘉𝘢𝘬𝘢."
"...Did you just speak Japanese to insult me?"
"No... That was Filipino."
"....."
...Yeah, your answer is believable.
Rolling my eyes, I buttoned my shirt and neatly tied my hair at the back. Just as I was about to leave, Otuko grabbed the back of my hem, hindering my departure.
"You can't leave."
Glancing at her, I turned my head to the side, unable to suppress a tongue click.
Earlier, I had questioned why I frequently depart immediately after the act.
"Just..."
Every girl I engaged with eventually turned like this.
"Please, don't go now..."
Otuko's gaze held a hint of tears.
It may seem subdued, but... Remember, yandere has five phases.
She's already at phase 1.
And thus, I decided to flick her forehead.
...
..
.
Moments later.
After letting the maid guide him, Saber finally joined the others, finding them seated at a table laden with exotic dishes, ready to eat.
"Where's your friend?" Solis, noticing him, asked in curiosity.
Feeling a bit awkward, Saber scratched his cheek before responding, "She's upstairs sleeping... She's a heavy sleeper, you see~"
"...hmm?"
Solis cocked her head to the side in confusion.
"Anyway, I'll wake her up after this... Her cheeks have been red since last night because of me, I'll take—"
"Morning..."
Suddenly, Otuko emerged from the corner. Saber was taken aback by her sudden appearance but shrugged it off, maintaining his composure.
Seeing her, Solis became slightly confused. She asked, "...Wait, I thought you said her cheeks were red?"
"Ah... Well... Erm..."
Otuko flinched and became embarrassed by what she heard. She glanced at Saber, then averted her eyes as soon as she met his.
Approaching her, Saber whispered, "Did you clean the room before coming here?" Otuko weakly nodded in response.
While this was happening, Odium, who had been silently listening to their conversation, took a sip of her glass of milk.
Dark circles under her eyes revealed that she hadn't gotten enough sleep the night before.
They did it till morning... She thought, glancing between Saber and Otuko, her face turning red as she replayed the scenes in her mind.
Saber noticed her and smirked; it was something only she understand.
'You were listening, weren't you?'
That day, Odium dedicated her entire time to a mission in the black market of their current city.
She didn't return for the whole day.
