Can a Kiss-Casting Curse Save the Detective Conan World?

[The main story is complete; bonus chapters are in progress. Also updating Can I Touch Your... Trash Can? (Katekyo Hitman Reborn and Jujutsu Kaisen crossover, and yes, I want all of them.)] As a goddess whose technique is even rarer than the Six Eyes, she is bound to a System and has skills like [Lucky Kiss], [Embrace of Salvation], and [Spiritual Union]. She can even bring her devout followers back from the dead. As a result, Hayakawa China has always been very confident in herself: there's no one a few kisses can't save. If there is, just kiss them a few more times. What's this? A member of the bomb disposal squad in the middle of defusing a bomb? Looks like bad luck might get him killed. Kiss him once. What's that? An undercover agent about to have their identity exposed? Kiss them once. And who is this? A fellow student who's gone astray? A single kiss won't turn them around, so I can only give them a few more hugs. China, diligently making the rounds and handing out smooches: "I told you kissing people could save them. Don't doubt me. Stop and let me give you a kiss." After graduating with dual degrees from the police academy and the jujutsu high school (?), and witnessing her close friend defect and the cruelty of society, she finally realizes that kissing people can't save the rotten mandarins or the Japanese political world. Instead, she'll only be manipulated, guilt-tripped, and exploited for her labor. Realizing that the rotten mandarins and the forces of evil are in cahoots, Hayakawa China says, "I've gone dark." She flips the table, leaves the association, and coldly works the distillery's hardest-working employees, the FBI, and the Japanese Public Security Bureau. Her lips are practically worn raw from all the kissing, but she finally achieves a happy ending in which everyone is saved. If someone told you that all it took was one kiss from her to change your fate, would you believe her? The blond Public Security Bureau officer, who is firmly convinced that Hayakawa China is a cult leader and an evil succubus and must be arrested immediately, is covered in marks and speaks heatedly: "Who said it only takes one kiss? That woman just... keeps taking... makes people sell their souls... plays with their hearts and then throws them away!" Kenji Hagiwara raises his hand high: "I believe her! I'm a devoted follower of China-chan. I gave her my soul willingly, mmmph!" Jinpei Matsuda and Hiromitsu Morofushi, who have been kissed time and again: "..." Shuichi Akai, who was never invited but lowered his head of his own accord: "Lady Luck is always on my side." While she goes around saving people, her friend who has gone astray wears a Buddhist robe and hands out flyers to passersby: "Friend, have you heard of the Hayakawa China religion? Join now and get a handshake ticket... Oh, not for you. I'm keeping this one for myself." [Warnings] 1. A satisfying power fantasy with a golden finger. The heroine will get the best of everything, while the power balance and plot remain reasonable. She has room to grow and won't be powerful enough from the start to beat WTW with her fists or kick XYJ. Early on, she's lawful good and somewhat weak; later, she goes dark and becomes extremely powerful. (Since there is a huge difference in combat strength between Detective Conan and Jujutsu Kaisen, the Detective Conan characters' physical abilities will be appropriately enhanced.) 2. Primarily Detective Conan and Jujutsu Kaisen, everyone gets saved, a harem-like love triangle, many characters are attracted to the heroine, and the main characters are listed in the supporting cast section. Multiple endings. 3. Fan works may inevitably feature OOC characterization or differences in how characters are understood. Please discuss things civilly in the comments. Theme: Even in darkness, keep your heart turned toward the light, and work hard to save everyone.
