In a world of monsters, beings stronger than kaijus, our main character follows a road to become a rider. In this world of monsters, hunters are common, monster hunters to be exact. They hunt and kill monsters for bounty, armor, clothes, food, supplies and for other reasons, it's their jobs. The monsters are dangerous and are huge threats to the people of the Monster Hunter franchise but these hunters protect them. Our protagonist wants to become a rider, a rider is someone that takes a monster egg from it's den and hatch the egg to raise the monster. When done, the monster becomes a monstie, which means that they are tamed and will feel a respect to their owner, like they were friends. A famous old rider named Red, the protagonist from the first game, is our current protagonists grandpa, his closest monstie is Guardian Ratha, which is a really strong Rathalos (a dragonlike monster) that protects the Hakolo Island (The home of our character) but got missing without a track after Red tragically died without any traces on why for both events. Our hero goes on a journey and finds rampaging monster that they have to stop and run into a mysterious girl, she knew Red and gives our main character an egg that comes from Guardian Ratha and our protagonist swear to protect it. The egg has a mysterious aura to it, hunters spies on our hero with the egg. A wingless Rathalos hatches from it. We meet many characters along the way and when they see this newborn Rathalos without wings, they get worried and wants it dead. This is because a legend as old as time says that one day, mysterious lights will appear all around the globe and when monsters comes close to the lights, they start to rampage and go crazy. The cause of the lights is because a wingless Rathalos was or will be born, the birth of this Rathalos would mean the end of the entire multiverse and outerverse, everything would be destroyed. This wingless Rathalos would become and the wings would grow and become terrifying and when that happens, it would destroy everything, starting with their universe. Everything would die. Which is why, the wings it would grow, would be called "The Wings of Ruin". This is why this Rathalos is therefore called: Razewing Ratha. That's what the legend says. Our protagonist believe that there's hope to change that and make Ratha the hero instead. That if the wings grow because of the power of kinship, he would instead be powerful and use his powers for good. But bounty hunters and a lot of tribes, thinks otherwise and try to capture Ratha and it's our job to prove them wrong and save Ratha (and the entire outerverse) from utter destruction. And during the story learn that everything may not be as it seems. This story, canonically, takes place a bit longer than a week, with the first 2-3 days being before Ratha's birth, by the end of the game, Ratha is only 5 days old. This game is also the introduction of the second strongest characters in all of fiction, Razewing Ratha. This was a plot description, not a game description, game mechanics and such are discussed seperatly.
