Fate/Improbability

Alberto Escarra, usually addressed simply as Al, had woken up as the son of some no name fairly young magus family after an untimely death in the world of Fate, or rather, Fate Grand Order. Whatever had reincarnated him had taken his left arm as the price for such a thing and considering his family wealth, it was a miracle he could even gain entrance to the prestigious Clock Tower as a student.... A path he'd ended up abandoning as soon as he turned 18 and pursued the medical field instead. Recognising the threat of making oneself known in the world he was now in, 'Al' had kept his talents and 'cheat' to himself. It didn't seem as though he could afford that luxury anymore, not when he all of a sudden found himself as one of the few survivors of mankind's incineration.
