Ultimate God Beast System

This is a world where Summoners rule the world. There's this trashy young man who wish to dominates the world but reality is cruel. He had a sickly body. He had neither talent for summoning or a special background but lo and behold a malignant star falls from the sky and hit him and a voice was heard in his head *Ding* "What a lucky bastard, I hit the wrong one. Anyways, Welcome to the Ultimate Godbeast System"
