Her name is Shen Yu Yehua, and she's a professional gamer. Her current main quest is to punish evil and promote good in the Detective Conan world, becoming a "star of hope" who saves people from danger.
The bad news: from the start, the System throws her into the villain faction and forcibly binds her to an exclusive negative talent, [The Immoral One].
[Morality is permanently fixed at zero. EXP gained from evil deeds increases tenfold, rewards for good deeds are reduced by 70%, and every good deed automatically gets a villainous filter!]
Looking at the System's daily missions, such as [Take out a certain elementary school detective] and [Seize power and become the new leader of the ultimate evil organization], Shen Yu Yehua slowly types a question mark:
Wait a second. Her clear win condition is to be a good person. What do you mean, giving her a negative talent that completely contradicts her main quest?
Are you deliberately making the game harder for the player?
Fine, then don't blame her for exploiting a bug!
A cruise ship is rigged with bombs, and no one can find the culprit?
No worries. She announces that she's taking the whole ship hostage, forcing the culprit to turn themselves in!
A genius boy is so oppressed that he wants to end his life?
She fires a specially made bullet that makes him appear dead on the spot, then carries off the "corpse" and saves him!
A bomber threatens the police with hostages, forcing them to choose between two victims?
She transforms into a crazed killer and seizes control first, scaring the criminal into calling the police for help!
The undercover agents on the good side are heartbroken, convinced that she's a tragic hero who has gone astray and is enduring humiliation for a greater cause.
The higher-ups on the black side applaud her, certain she's a born evil, cold-blooded criminal mastermind.
Looking at the EXP bar in the background skyrocketing tenfold, then at the string of good-side undercover agents, young detectives, and innocent citizens she'd rescued along the way by using villainous methods...
Shen Yu Yehua sighs and shakes her head. "I'm really just a player trying to clear the game."
Please note before reading:
1. Timeline chaos warning! Major character OOC warning! Canon changes and original settings warning!
2. Main plot, power progression, slow burn.
3. Focuses on the protagonist. The heroine is a Mary Sue and an overpowered heroine. Open ending, with different endings in the bonus chapters.
4. An atypical fourth-dimensional catastrophe. The heroine's thought process is vastly different from a normal person's, but she is not a fun-seeking troublemaker!
5. There is a lot of people jumping to conclusions and misunderstanding each other, including plenty of scenes where the heroine and both the red and black sides imagine what the others are thinking.
6. Primarily Detective Conan and Magic Kaito, with small amounts of other anime and manga. You can follow the story even if you haven't read them.
7. Shuichi Akai and Akemi Miyano are not a canon pairing here!
