MTL - Transmigrating as the Younger Sister of a Bigshot with Multiple Identities - Chapter 5 it's not fair to my sister

A merciless and unforgiving world where a common cold could kill you, a world where survival of the fittest applied—A world where humans aren't at the top of the food chain.A world where the roar of predators echoes through the wilderness, and the threat of being hunted lingers around every corner. A world where the natural elements are both beautiful and deadly, with raging storms and scorching heat waves that can wipe out entire communities.Every day is a battle for survival, with individuals and groups fighting tooth and nail to secure food, shelter, and water. The weak and vulnerable are often left behind, their fate sealed by the brutal law of the jungle.And in this same age, same jungle there was a young boy, whose fate changed when he heard an unknown voice in his head.Garnt woke up feeling a little better after he was on the verge of death because of a single wound he suffered from hunting, and the first thing he noticed was that everything around him looked foreign to him, even though the cave he was lying in was supposed to be his home.While he was unconscious from the injuries, Garnt saw several things he couldn't even understand.He saw people using brick-like equipment to communicate with each other and flying monsters that happily served humans by taking them inside their bodies. A bizarre world where everyone covered their bodies. He saw giant structures that stood even taller than the largest caves he had seen and suddenly a voice questioned his mind about what he witnessed.[Why do these waters look muddy? Why don't you filter them?]What are you talking about? This is how they are supposed to look.[Why are these weapons so blunt?]They are sharp enough for me.[Where are your clothes, Don't you get cold?]What are clothes, I don't know.[Why do men and women look like they don't feel anything while having sex? Wasn't it supposed to be romantic and sensual?]What do you mean? It is just an activity for procreation.After witnessing such a world, Garnt felt like they were missing something important. His current status looked like a living hell when he compared it with the vision he had. But was that vision real? Does something like that really exist?[Yes, it exists. Do you want to see that world? I will help you, but in exchange, you should make my dream come true.]

Meet Sora and Shiro, a brother and sister who are loser shut-ins by normal standards. But these siblings don’t play by the rules of the “crappy game” that is average society. In the world of gaming, this genius pair reigns supreme, their invincible avatar so famous that it’s the stuff of urban legend. So when a young boy calling himself God summons the siblings to a fantastic alternate world where war is forbidden and all conflicts–even those involving national borders–are decided by the outcome of games, Sora and Shiro have pretty much hit the jackpot. But they soon learn that in this world, humanity, cornered and outnumbered by other species, survives within the confines of one city. Will Sora and Shiro, two failures at life, turn out to be the saviors of mankind? Let the games begin…
