Genius girl + transformation + single girl Ai Haibara

Ruan Yechuan, who considers herself a genius, was defeated by the gacha system—a single ten-pull directly pulled her into a grand gift pack from another world.

Time travel it is fine, gender swapping extravaganza? Okay, she'll take it.

He accepted it; at least he had transmigrated into the goddess he had always longed for in "Honkai Impact"—"Black Tower." But before she could even get used to her new skin, an even bigger "surprise" came her way: the "elixir of immortality" from the world of Detective Conan allowed her to live for two centuries with this stunningly beautiful face.

To escape the shadow of the side effects of immortality, she chose to return to the eye of the storm—the dark organization that created the pills. Unexpectedly, stepping into the organization, she ran into her nemesis: Shiho Miyano, codenamed Sherry.

An 80-year-old relic is completely controlled by a genius young female researcher.

Absurd! Lin Yechuan (Black Tower) was furious... but the aroma of the dish the other party served instantly shattered his fighting spirit. Waaaaah, this cooking is just too unfair!

Being manipulated was already frustrating enough, but Shirley's behavior became increasingly strange:

The glint in his eyes as he secretly added something to her food, the intense gaze that sent chills down her spine… This wasn’t going to happen! Run, she had to run!

(Transformed into a yandere/single, impossible to marry, main plot: cult building, farming, establishing power, and combat) (ps: the protagonist is purely evil and a scumbag woman in the early stages, including but not limited to PUA. Other female leads may be involved; please do not read if you dislike this.) Ren Xiaolu swore that he never imagined that one day, he would choose to become a witch because he wanted to escape his sister's clutches. Ren Xiaolu, male, 19 years old, a sunny and cheerful young man, was imprisoned in the basement of his house by his sister after she discovered his heretical identity, undergoing "corrective education." From that day on, Ren Xiaolu completely understood the true meaning of the term "yandere." His sister is a demon in the guise of a saint. By completely changing his appearance and even his gender, Ren Xiaolu finally temporarily escaped his sister's clutches and began a fulfilling and easy second life—or so it should be. But with the binding of the "Heretical System," the approaching survival crisis, and his sister hiding somewhere, all the small joys Ren Xiaolu sees before him are like a dream, about to shatter in the next moment. To protect everything before him, he puts on a short skirt and becomes a natural disaster…

The female lead in the "Sugar-Free" series: Kiana + Mei

She was overly compassionate in the early stages, but went mad later.

Notice that Otto, who was bored out of his mind, cloned hundreds of Kiana clones, but unsurprisingly, only K423 possessed self-awareness.

Just as the remaining clones were buried by Otto's men, the music from Plants vs. Zombies began to play, and a hand emerged from the ground. "Honkai Impact 3, welcome your king!"

"Even if I, Lina, am poisoned to death by Honkai energy, die outside, or be used as a guinea pig by Mebius, I will never become a beautiful girl."

Soon after, surrounded by countless beautiful girls, Lina said with a silly grin, "Wow, it smells amazing."

[Transformation] [Never Marry] [Narcissus]

Transmigrating into a bizarre and restricted game, Su Youdie becomes an S-class anomaly prophesied to destroy the world.

Thinking it was a perfect start, I never expected that the so-called world-destroying anomaly would actually be a frail girl who was light-bodied and easily pushed over.

The good news is that her Witch's Eyes possess a god-like ability to transform into the other person's "fear object" after they make eye contact.

But knowing the game's plot, she knew that she was just a fragile vessel with empty power, destined to be defeated by the male protagonist, have her demon eyes forcibly gouged out, and become a stepping stone for someone else.

"This power is too dangerous. For the sake of humanity, please give it to me."

Faced with the male lead's moral blackmail, Su Youdie retaliated with an elbow strike: "Where did Ruozhi come from? I'm your Die! I've never seen anyone so shameless!"

To avoid a disastrous ending, the girl decides to forge her own path to defeat the protagonist...

Since you are all afraid of me, then I will become fear itself!

In the pitch-black corridor, the light bulbs flickered, and tiny white feet stepped over the corpses.

She appears to be a delicate girl as white as a sheet of paper, but her body harbors hundreds and thousands of evil creatures: Sadako, aliens, zombies, snow women, chainsaw maniacs, ghost dolls, spider buses, and many more witches.

They are all embodiments of fear, and they are all part of her.

The girl revealed a wicked smile and said—

"Don't run away, I'm not scary at all~ Let me see what you're afraid of?"

"Huh? You're saying you're afraid of your wife? You want me to become your wife? Dream on!"

When she came to her senses and looked down at Earth, she couldn't help but sigh softly, "I really didn't want to destroy the world QAQ"
