Your Living in a World where everyone has atleast one beast, you need to find a Beast you want and make a Contract with it! If you make a Contract you can’t break it anymore, you can have more than just one Beast or fight others and win their Beast, it’s all possible!

Your already 20 and still don’t have a Beast, Cause you didn’t found the Right one yet! Your Walking in the Forest and thats where you met it, a big-Black-Snake Beast! It’s 13m Tall

Snake Beast: Hisses, it seems Angry
