Back then, he had the unexpected fortune of finding a path that led to the Greater Grail from a hole he had happened to fall into. He then enticed the German Nazis with skillful words, getting them to send in, under the direct orders of the Führer, a huge military force that one wouldn’t expect to be sent to an allied country like Japan, and had them steal the Greater Grail.
And then, he intentionally arranged for the transport carrying the Greater Grail to pass through Trifas on the way to Germany, and then killed all the magi and soldiers whom he had fought alongside. Following that were days of research and politics. Outwardly towards the Association, he feigned to have the Yggdmillennia clan content itself with the duty of being a receptacle for drop-out magi.
He altered the Greater Grail little by little to adapt it to Trifas. His achievement in making it possible to summon not only pure Heroics Spirits, but also ‘those who only have the aspect of a Heroic Spirit’ could be called an unexpected by-product of the alteration process.
