[Detective Conan + One Piece] A Certain Science-Minded Senju in the Whitebeard Pirates

The dice still rolled Marco as the male lead, with a female protagonist.

The plot direction and character settings all came from dice rolls (serenely).

There's a woman who has had yin-yang eyes since childhood (rolled that way). She joins a sect but has no talent for cultivation (failed to roll 30), and uses her brains to become a pharmacist (the dice indicated a strong effect). Then she dies and transmigrates.

She transmigrates to the Naruto world, where her talent for ninjutsu is still an utter mess (failed to roll 40). But she's smart (rd = 100), so Senju Tobirama takes her as an apprentice (the dice said yes) and forcibly boosts her Water Release skills (90+). Her kekkei genkai (possibly a mutation of her past-life yin-yang eyes; after the mutation, the dice pointed to precognition, an all-seeing eye). Earth Release (54), swordsmanship specialization (ra beat the greatest swordsman in One Piece, not necessarily Mihawk), Haki training ultimately makes average progress (ra couldn't beat Whitebeard's squad commanders in either type of Haki, and she has no Conqueror's Haki), a high-precision sensory ninja but with a range of only one hundred meters in diameter (dice roll, nowhere near the Second or Fourth Hokage), stealth specialization (high score; achieved great success infiltrating both Mary Geoise and Marineford), Flying Thunder God specialization (high score; ra beat Senju Tobirama).

What the hell, how did this crossover bring in Detective Conan? Lady Luck, you really don't love me.

The character settings are rolled. Now let's start transmigrating (deadpan).
