Editing Kono Naka:Volume 1 Prologue (section)

===Part 1===
"Onii-sama."

A soft whisper came from a young girl.

Sitting on a chair, Shougo Mikadono, who was about to enter the world of dreams, suddenly opened his sleepy eyelids and glanced at the four corners of the room.

"Is there anyone here?"

However, there was no one in the room aside himself—what's going on? Did I mishear?

Today is the day when the funeral of the internationally-known Mikadono group's representative, Kumagorou Mikadono, is held.

It's February, where the cold weather hasn't left yet. Shougo still didn't have the time to feel saddened by his father's death, and since the early morning he has been running around, busy taking care of multiple matters with his mother.

As things finally came to an end, Shougo could take a break in the visitors' room. He was so busy that he didn't have time to change into his funeral clothes, and became sleepy with his school uniform on him—at that moment, he was awoken by a mysterious voice.

"Onii-sama, I'm here."

The voice came to him again, this time with the noise of the windows being knocked on. It seems that it came from the outside.

Shougo turned his body and lifted his head. Above the bookshelves, there was a small window. Outside the window, snowflakes were rustling and falling. There was someone below the window who was knocking on it, and the clenched fist was barely visible.

This window was made to gather sunlight, and was even higher than Shougo's height, and there seems to be someone raising her hand outside the window----

"Who is it?"

"It's wonderful, I have always wanted to see you, but I couldn't meet you with that many people. Finally, I can finally talk with my brother, do you know how I was longing for this day, wuuu..."

"That's why I'm asking, who are you?"

"I'm Onii-sama's little sister."

"Little sister? What do you mean, I'm an only child."

"Really, Onii-sama won't be alone. From now on, I'll always be together with you."

"Together? What the heck do you mean?"

"I'm here in order to marry Onii-sama."
