Lord of End of World - Chapter 146

After a shocking reincarnation, our hero opens her eyes to a new (and messy) world the last thing she remembers is reading Lady Viper’s Vow, a dark fantasy novel about a cruel, misunderstood villainess and her path of doom. But when our protagonist finds herself reborn right in the heart of an attack, she’s moments away from a second, way-too-soon death. Just as she’s about to face the end, a mysterious “system” pops up with a single mission: Level Up or Die Trying. It’s bossy, snarky, and her new best friend. As she levels up into a borderline-cheater powerhouse, she discovers her fate isn’t to be a hero, a princess, or even a sorceress, but to protect the one person no one ever expected her to side with: the villainess herself.

Being given a chance and reincarnated is nice and all, yet why do I have to become that male friend who just watches the protagonist flirting with his harem?---World: Kaguya-sama: Love Is War - Hyouka ----

After dying from a strange terminal illness, Ling Lan was reborn into a world 10,000 years into the future. Although she dearly wished she could just live a peaceful and uneventful life in her new healthy body, fate had other plans…

Forced to disguise herself as a boy just so she could inherit her deceased father’s premium military benefits, Ling Lan’s journey to adulthood was full of challenges. After much difficulty, she finally turned sixteen when she could drop the charade. But before she could grasp her newfound freedom to get married and start her own family, a twist of fate results in her being thrown into the Federation’s top military boys’ school.

With these twists of fate, Ling Lan had little choice but to walk further and further down a path of no return, one of cold and aloof dominance…
