Armando told Morgana and Arriane about his story in his previous world before he acquired the system.
It turns out that Armando is not from this world or from this earth's dimension like the system. Armando is actually a brave and courageous leader of their department working for the government, just like his current position now. Unfortunately, he schemed by someone in their department who envied him and wanted to take his position. That person schemed against him to have him killed, but before Armando took his final breath and lose his consciousness he saw a light and he actually thought that it was the gate of heaven. When he opens his eyes again, he finds himself lying on a hospital bed, with the same name, body and looks but in a different world.
