Prologue

Once upon a time, in a certain place, there lived a bluebird. 

The bluebird was said to grant wishes, and granted the wishes of many people who lived there. 

One day, an evil person made a wish to the bluebird. 
The bluebird granted even their wish, and as a result, many people were made sad. 

The bluebird did not know right from wrong. 
They simply went on granting people’s wishes. 

Before long, all the people vanished, and the bluebird was left all alone. 
And everyone lived happily ever after. 

“…How many times have I read this?” 

“Oh, no. It’s nothing. I was just curious.” 

“Yes, it is quite worn. Perhaps I’ve read it many times.” 

“What if the bluebird really existed, you say…?” 

“Hmm… Well, I do have a wish, yes.” 

“But I can’t tell you, because it’s too embarrassing what it is.” 

“Ahaha, sorry. Don’t be mad. I’ll tell you another time.” 

“So, we’ll play again tomorrow… It’s a promise.”
