Ascension of a Saiyan {Completed}

Y/n L/n, an average student in Kuoh Academy. But he is not your average student. Having banished and neglected from his universe because of being very powerless against them except for four people and they are Son Goku, Whis, Beerus and Kaioshin. He was also neglected by everyone around him and overall he is just a wimpy mortal. Now when he arrived at Universe DxD, he is just a simple working student. He work as a cook from the Kuoh Academy's Canteen, while he attends to Kuoh Academy where male students doesn't exist except for you. With the help of his loved ones and friends, he will achieve the rank of being an omnipotent and omniscient deity because that's his dream. But the question is how will he do that? How will he achieve that kind of power if he is just a wimpy and very weak mortal? Only time will tell.
