Twenty years before the time of time of Fate/strange Fake, Dilo was appointed by the Church to a mountainous region in Spain. Taking it upon himself to investigate rumors of evil spirits in the mountains, he came upon the young Hansa Cervantes, his guides scared off by the sight of Hansa eating dried meat from a bear they mistook for the flesh of a climber. Deciding that Hanza was not the cause of trouble, he proceeded on his way, only to be later confronted by Hansa, who opened up to Dilo after conversing with him. He told Dilo that his village that had been previously located on the mountain was attacked by a Dead Apostle, calling it a "goblin", and that even his own mother died from wounds from the attack. After several more visits, he brought Hansa back to the town with him.
Several months later, Dilo brought Delmio Cervantes to the orphanage in which Hansa was now residing. Dilo chose Demio due to his prowess in martial arts, believing that Hansa's interest in such things and a strong teacher would help develop him. Delmio is quickly surprised upon testing Hansa's prowess, soon adopting him as a foster child and training him.
