A simple idea I had some time ago and wrote down out of boredom, so don't expect too much because I didn't put any real effort into it. Just a Fate/stay night Seraph of the End twoshot about one of many possibilities how to do it.

Just a challenge I came up with, would be honored if it was accepted

Yu never had the best of luck. Sure he has an awesome friend from another world and a vampire-turned-demon as his weapon. But he died using a forbidden power and almost had his soul taken by angels! But his friend and demon attempted to stop the process, sending him into an entirely new world and now fighting in a magical tournament. Yep, definitely unlucky. Magus!Yu [4thHGW]
