A deadly weapon

At the base of the trunk was a large sealed brown envelope. She brought it out and found a pair of scissors on her dressing mirror which she used to cut it open.

"What's this?" she asked herself again, as she poured the contents out. They were a bunch of papers, carefully folded.

She unfolded them and a blueprint was revealed to her. There was a smaller envelope on top of the blueprints and within, she found a letter.

Dear Miss Chi, 

I have heard about the search for your missing son and the involvement off the proprietress of Cloud schools. As your emperor, I take it as my duty to assist those who contribute to the growth of our beautiful nation so I am involving myself in this matter.

I have long heard about the misdeeds of Cloud school and with my authority, the national security agency has been monitoring it for two years.
