The Miku I ordered has arrived.

I'm going to give it to my niece as a present.

My niece has a congenital defect in her throat...

...and she can't speak.

Even though she loves music, she cannot sing...

I felt so sorry for her.

At first, she was looking at the package with a face that said "What's this thing?", but...

...as soon as I gave her a little demo, her curiosity exploded.

It was the first time I saw such an expression on her face...

Her eyes were sparkling just like those of a shoujo manga heroine.

Mikkuing down the niece (abbr.) みっくみくさせる = to get knocked down by Hatsune Miku's charm
