The Oath Of A Warrior

Y/n Hyoudou was the adopted sibling of Isami Hyoudou, younger by a few months in age. In contrary with his sister, he did not have a Sacred Gear sealed within in his soul...a normal human to put into words. One day, he was asked on a date by a unknown individual who held the intention of murdering him. However, he will rise again and become one of the most powerful figure history has ever known.
