"Welcome to my home."
I gave a small nod, staring blankly at the huge mansion in front of me.
"As expected, Sister Mio's house is really big,"
Yae said with a teasing smile.
Mio smiled sweetly and poked Yae's cheek.
"Stop teasing me. I already brought you here yesterday."
"Hee hee hee." Yae grinned mischievously, sticking out her little tongue and acting cute in front of Mio.
Mio smiled wryly and jokingly pinched Yae's cheek.
"Ow, that hurts—sorry, Sister Mio."
After Yae sincerely apologized, Mio finally stopped pinching her.
Yae puffed out her cheeks while rubbing her slightly swollen, reddened face.
Seeing how close Yae and Mio were, I felt relieved as Yae's older brother.
In this world, someone was actually treating my little sister well—and as her big brother, I was naturally grateful.
Perhaps sensing my gaze, Mio turned toward me and smiled gently.
"I don't mean to take Yae away from you, so don't worry."
"S-Sister Mio! What are you saying?!" Yae cried out, her face turning red with embarrassment.
Mio giggled softly, winking her clear, beautiful sapphire-blue eyes at Yae.
Mio stepped closer and whispered into Yae's ear.
Because they were too far away, I couldn't hear what she said—but I was sure she was talking about me.
Honestly, I didn't mind being talked about by Mio or Yae.
But what came next made my heart feel uneasy—Yae suddenly blushed and looked at me with a shy expression.
Thump—thump!
The truth about our sibling relationship flashed through my mind.
'No, Yae is my little sister! I must not fall in love with her!'
"Ahem! So, which dungeon are we going to explore?"
Mio immediately started fiddling with her phone and showed us an image of a dungeon gate I had never seen before.
"Which dungeon is this? I didn't know there was one like this nearby."
Mio smiled brightly, looking cute and sweet.
"Of course you wouldn't. It's a private dungeon owned by my family."
I tightly closed my mouth, left speechless as I stared at Mio.
"As expected of Sister Mio!"
Mio nodded gently and led us into her house.
After calming myself a little, I raised my hand and asked hesitantly,
"What are we doing here?"
"Getting equipment. Even though the dungeon we're going to is only level one, with your current weapons it would take too long."
I gave a bitter smile and nodded in agreement.
"Akio, since you're a man, you'll choose a sword, right?" Mio asked.
"Yeah. The only weapon I can use is a sword."
Mio flashed a lovely grin and took out a high-grade sword that was obviously far more expensive than the one I owned.
"Use this. With it, defeating goblins should be easy for you."
"…"
My eyes were fixed on the long sword, which emitted a blood-red aura.
(Vampire Sword — absorbs the enemy's blood to increase attack power, max +1000.)
Okay, one word wasn't enough to describe the sword in my hands.
If sold at an auction, this thing would definitely fetch an outrageous price.
"Isn't this too valuable?"
Mio casually waved her hand as if dismissing my concern.
"Compared to your potential, that sword is just trash."
"…"
"I also want a good dagger," Yae said.
Mio gave her a small smile and walked off, returning with a pair of daggers that she handed to Yae.
"For a cute and sweet Yae, I have twin daggers."
(Twin Daggers — Attack +200.)
"Wow! Thank you, Sister Mio!"
Yae happily accepted the daggers and excitedly kissed Mio on the cheek.
It was quite a rare sight to see two beautiful women hugging and even kissing cheeks like that.
If I didn't know the reason behind it, I might have suspected they had a questionable sexual orientation.
"All right, the weapons are done. Now all that's left is choosing suitable armor for you two."
"Eh? What do you mean by armor?"
"Of course armor for dungeon exploration. With a full set, you'll gain very useful attribute bonuses for combat."
"…"
At this point, I didn't even know what to say about all these sudden privileges.
Time flew by while we chose our armor, and soon we were standing in front of the level-one dungeon we were about to enter.
As soon as we arrived, Yae and I were bombarded with questions by the association staff, only stopping when Mio stepped in after they began to suspect us.
In reality, even though this was a private dungeon, association staff were still required to manage everything. That was why they were stationed here.
"Want to try it now?" I asked.
Mio gently shook her head.
"No. We'll do it after entering the dungeon. I want to see the difference before and after using the Harem Leveling skill."
"All right, let's move."
Mio nodded gently along with Yae.
And so, we entered our first level-one dungeon together with Mio Khalifa.
