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.

Why would I not want it? I couldn’t ask for anything better!!”His sword sweeps across the Divine Continent for seven days and nights, moving 90,000 miles through the starry skies, unhindered.He slays saints and buddhas in Heaven, slaughters demons and devils in Hell, sweeping away all the grievances in his heart.

Joseph Knox, one of the most prolific and well-known serial killers on the planet.A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world
