[Book Transmigration] The Supporting Actress Is Cool, Domineering, and Bold

Leng Leng, a famous G Star celebrity, the planet's number one beauty, ranked second in overall strength and first in combat ability, secretly used a transport pod to search for her younger sister, who had accidentally ended up on Earth. But who could have guessed the coordinates would be wrong? By chance, she wound up inside the world of a reborn Earth romance novel. She even became the novel's biggest supporting villainess, the reborn heroine's stepsister. A villainess who died after dieting for love. The heroine's older sister is a top student, a beauty, and a genius screenwriter. The villainess's younger sister is a poor student, a beauty, and an idol. When the alien Leng Leng transmigrates into the role of a doomed supporting villainess... You fish-brained humans, you useless weaklings with negative-five combat ability! Stay away from me! Keep pestering me, and I'll wipe you all out! What the heck, this is the man I like. Are you insulting me? Your combat ability is weaker than mine! Your intelligence is lower than mine! And more importantly! I! Don't! Want! To! Have! A! Mixed! Species! Baby! And that's the story of a cool, aloof, high-and-mighty alien big sister (so cool, so dominant, so bad) who crosses the stars to find her sister, and incidentally conquers a whole bunch of Earthlings.
