A Nasuverse OC! Grant is a moderately infamous enforcer of the Mage's Association from America which to the magical community is still kind of like the Wild West. After taking down numerous evil conspiracies, magical petty crooks, and generally saving the day enough to build up a bit of a legend, a two-bit necromancer got lucky and took him out. However the Necromancer goofed and used his body for an experiment. He replaced Grant's heart with a magical clockwork heart that would bring him back to life as long as it was fueled by magic. Grant woke up, broke free, killed the necromancer, and went back to work, though now with a life threatening addiction to magic. He joined the Holy Grail War in the 1920s, and since he had technically died, when he summoned his servant, he summoned himself.

Here is the thread where he summoned himself. Unfortunately the PSL never really got very far. Also obviously he has a different PB and a different journal now.
