Naruto: The Gears of Fate

[Beloved, irresistible heroine × one-sided crushes from everyone × unwitting flirt × sweet, innocent-looking but secretly cunning sunbeam × love rivals galore, featuring an original male-male side pairing] “The heroine starts out as a genuine, adored sunbeam, then becomes a cunning little fox.” She's Konoha's cherished little sunbeam: lively, bright, passionate, bold, beautiful, sweet-tongued, and good at acting cute. Wherever she goes, she warms the place up. Think she's flirting with you? No, it's just a passive skill: costs no mana and has no cooldown. That is, until she's forced to leave the village and regains her memories. She takes her older brother by the hand and says with a beaming smile, “I want to join Akatsuki.” Her brother looks at his sweet, harmless, well-behaved little sister. “Are you sure? They're all dangerous people.” She nods enthusiastically. “Mm-hmm, absolutely sure~” Her brother spends every day worrying that those lunatics will bully his soft, adorable little sister. As it turns out, he underestimated her. Love rivals galore: A crowd chases after her, asking, “Xiao You, who do you really like?” She blinks innocently. “I like everyone~ We're all friends~” “...Friends?” “That's right, you're all such good people~” A confirmed mass distributor of friend-zone cards! Her “friends,” each falling for her all on their own, are head over heels: “She's so sweet. I like her so much~” Meanwhile, the people she's cut down stare at the girl standing amid a sea of corpses, her clothes spotless, tilting her head with a sweet smile. Their eyes widen in shock: “You call that... sweet and innocent???” She looks baffled. “I just want to save the ninja world and open a chain of dessert shops on the side... I'm focused on my career, so why is everyone acting like they're in a romance novel?!” In one sentence: The evolution of a beloved, irresistible girl into Akatsuki's most beautiful fox (crossed out) thorny rose.
