The ace killer of the 21st century, after being murdered by her own relatives, time-traveled into the body of the useless, weak, and nymphomaniac third lady of the Prime Minister's Mansion. What kind of adventures will she have? Is your mysterious beast very powerful? Sorry, I fed it to my "son" just now; is your master very good? Is her master as good as hers? You do it thousands of times every minute and every second; an alchemist? Sorry, sister, I am just a god. She plays tricks on the people in this world, but... Who can tell her where this monster who pretends to be crazy and acts stupid comes from? Hey hey hey! I mean you, don't fool my cheap daddy! This novel and its characters are purely fictitious.
