Reborn as guardian of an omniverse(PJO X DXD crossover) RGO

When you are about to die, your entire life flashes through. When I saw my life and how I wasted my talent by overestimating my limits, I was resigned. From the life of a genius, I fell into a worthless college student with below-average grades and nothing to show for himself. So, when the primal goddess offered me a chance for a second life, I accepted. Now, even when the odds are stacked against me, I will become someone great.
