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 ----

Perla had always felt a longing for adventure, stifled by the rules of her strict upbringing and surrounded by her older brothers free to do as they wanted. She longed to carve her own path, to seek out excitement and perhaps even a little romance along the way. One day, while escaping yet another tedious piano class, she stumbled into the hollow of a massive tree. At its base, a mesmerizing green light beckoned her, and before she knew it, she was transported to a bizarre forest teeming with colossal, long-extinct creatures and menacing carnivorous plants.This was the realm of Beastkin, where men could transform into mighty beasts. Here, the constant threat of war had led to a peculiar imbalance, with most females giving birth to male Beastkin, resulting in a dire shortage of women. The land was a battleground, filled with mercenaries and adventurers seeking glory. While the males formed companies to embark on quests, their females stayed behind, living a life of comfort. But not Perla—she was determined to break free from the mold, to grow stronger, and to join her new love interests on exhilarating escapades.
