At fourteen, Shiho Miyano was under the control of the Black Organization, diligently skipping grades in America, over and over, while researching the drug APTX 4869, over and over. Then, perhaps because there were too many undercover agents in the Black Organization, she woke up one day to find that word of a "drug of immortality" was spreading like wildfire in the underworld.
Even the most rational person could hardly stay calm in the face of a drug said to grant eternal life, let alone a group of cold-blooded, violent criminals.
"XX, you don't want your nemesis to still be alive and well thanks to the drug after you're dead, causing trouble for your family, do you?"
In the eyes of the powerful and aging, this tiny pill was like the Golden Apple in Eris's hand. If they couldn't have it, they would destroy it.
A genius scientist and the chief researcher of APTX 4869, Shiho Miyano was exhausted, both physically and mentally, after surviving assassinations, poisoning, and a whole string of other incidents. She accepted the Vongola family's invitation and took shelter under the umbrella of the underworld's largest mafia family.
However, the Ninth Vongola Boss, also powerful and aging, didn't make the offer she had expected. Instead, he gave her a kind yet inscrutable smile.
"Shiho, go to Namimori in Japan and help my successor, the future Tenth Vongola Boss, Tsunayoshi Sawada."
...What?

"My research wasn't aimed at a drug that could fulfill this kind of dream. It was about something terrifying, whose value almost everyone on this planet fails to recognize, like the Hina dolls that only girls in this small country seem to care about."
[Reading Guide:]
1. Just an ordinary story based on a random idea. Not recommended for serious reading.
2. This story is extremely, extremely ridiculous Mary Sue OOC. Don't assume anything the author writes applies to the original characters. Anything that differs from canon is the author's own setting.
3. Shiho Miyano is Ai Haibara from Detective Conan, but there won't be much content involving the Detective Conan gang.
4. Happy ending, pairing undecided, whatever happens happens, perhaps no pairing.
Theme: Why did the genius scientist change jobs?
Because it's the tenth generation of Vongola who can protect Shiho wellww
Damn it, squat down and update
Wow, look what I found, it's Aibao! [Let me be healthy]
