Two Cats Fell Down the Dragon Wall (High School DxD x OC)

Ever since he was socked in the guts by a certain white-haired Nekoshou as a child, Ed Sakari has made a promise to become the strongest (OF THEM ALL!) in order to one day surpass his so-called rival.

However, one tiny little thing stands in the way; he's a plain old human. In other words, a race mostly ignored by everybody else as weak. Possessing no Sacred Gear, no mystical ancestral weapon and unable to use even an inkling of magic, his goal might just be impossible...

But no matter! As he himself often proclaims with boundless optimism and irritatingly loud volume: "Hard work beats even the lazy gods!"

And so, follow the misadventures of Ed as he strives to be the strongest (OF THEM ALL!), makes friends, lovers and foes far above his weight class, saving the day as well as constantly bothering his rival about their one-sided rivalry.
