Albedo Caelum : Reflective Sky

Tsunaoko Sawada just wanted to play volleyball professionally and actually survive long enough to become middle-aged. Maybe even grant Nana and Iemitsu's greatest wish and give them grandchildren. She had long since accepted a possible involvement with the Underworld, even if it was purely by association with her bestie and his club (which was really just the Hibari Protection Squad but don't tell him she said that). Just as she accepted that she would forever be immortalized as Dame-Tsuna. But, unfortunately, someone had the bright idea to have the next heir for the Biggest and Most Powerful Mafia Famigila in World to be a mostly untrained civilian and everything went to hell. Because having a calling to be the next Mafia-lite Magical Girl, one hell of a tutor with a hobby of shooting her down, and a nonrefundable offer to become the Vongola Decima was not in her itinerary.Things had been so much easier when all she had to worry about was how much cost in damages the Committee owed and whether or not Kyōya would bite her to death again for throwing him another surprise party. It really made her wonder if it all would have been better if she had just stayed dead.[Warning: slow burn; extremely AU]
