My little sister is too cute, so I have to protect her!

"Ooh! Nii-sama, look! It's a haunted house!"

Mio pointed to a nearby stall. Apparently, some class decided to use the old warehouse as a haunted house. I heard that the freshmen this year got some superb skills in special effects too. Might be interesting...

"Let's go, Nii-sama!", she dragged me towards the haunted house without a single ounce of fear.

Somehow... I just couldn't help but think what is going on in her head...

************

[Meanwhile, in Mio's head...]

'Kukuku... Nii-sama fell into my trap perfectly!'

'Inside the haunted house, I will act scared and take the chance to pounce upon Nii-sama!'

'He can't resist me either, because this is a valid reason!'

'Muahahaha!!! I'm such a genius!!!'

************

"Nii-sama, don't let go of my hand, okay? So you won't feel scared!"

"Alright, alright, Mio."

I gripped onto her hand as she told me to. Somehow, I felt like this is all planned out by Mio... But it's probably just my imagination, right?

As we started to walk into the haunted house, Mio drew herself closer to me. She is so close that I can smell her nice scent. However, I must not be distracted. I started to walk forward through the path they provided.

"Is that...?"

Suddenly...

"Boo!"

"Kyah! I'm so scared, Nii-sama!"

At the same time the ghost came out to scare us, Mio clung onto my arm like a cute little kitten. Ah~ I remember this softness~ It's tender softness can always calm down my heart~~~

As we kept walking through the haunted house in that posture, Mio suddenly stopped walking. She immediately took out some kind of glow-in-the-dark slab of wood and raised it into the air. What in the world is she doing...?

As I was wondering that, the students who acted as the ghosts suddenly constructed a wall by moving pre-built pieces of wood around us. It appears that the wall is made of wood and is very sturdy. The height of the wall is as high as the height of the warehouse itself.

"Good work, everyone! You may leave now!"

"Yes, ma'am!"

I suddenly realized that this was Mio's doing... again...

"Mio..."

"Yes, Nii-sama?"

"What are you planning again?"

Before she answered my question, she turned towards me with eyes as fierce as the eagle.

"Nii-sama..."

"Before we came to the haunted house, the cafe was your domain, yes?"

"But now... In the haunted house that my class operates, you are now in my domain..."

"And in here, I am the queen..."

"Therefore, Nii-sama..."

"Obey my commands!!!"

Before I could do anything, a collar materialized from her hands. She immediately moved closer to me in an unsettling manner.

"Come here, Nii-sama..."

"M-Mio!!! What are you doing?!?!"

"Heeheehee..."

I started to run away from Mio. During the chase, I was almost caught a several times, however, I always managed to dodge using small manoeuvres however...

"Sh*t! The wall is closing in?!?!"

The walls on four sides that were surrounding us suddenly moved in towards me, limiting my space of movement. Mio is now getting closer and closer to me with every second that passed by. Finally, when I was cornered...

"Give up, Nii-sama... Be a good boy and accept your fate...", she smiled devilishly. In her hands, the collar that gives off a dull colour moves in closer and closer to me with every second...
