Spada left home because his parents neglected him in favor of his six older brothers, who were jealous of him being stronger than them. This jealousy eventually turned to violence, resulting in them trying to poison him with scorpions, and even putting glass in his food. During this time, he lived in the sewers below Regnum, and abandoned his noble upbringing to become somewhat of a delinquent. Spada is first seen being arrested in Ruca Milda's hometown, though the group meets up with Spada at the research lab when they are being held prisoner. At first, Ruca thinks Spada is a punk and gets scared of him easily. However, Illia Animi and Spada get along, joking about ways to tease Ruca for his timid nature. A few minutes later, they are taken to a test ground and forced to fight a Reborn. After the battle, Spada uses the power of his past life Durandal to take out a past member of Ratio. After this, he joins the group, and they are sent to the Western Battlefield to fight in the war.
