Well, it is after his death when Ruby and Iske are already king and queen that they discover an illegitimate child in that same orphanage that Ruby stayed in as a child. He was around two years old at that time and was Enzo's daughter with some woman he was with. Iske sends Ivan and another guy who unfortunately I can never remember the name of to get the child because he is Ruby's nephew. He is an agitated little brat who is adopted by this other paladin and grows up with Ruby's son and Ellen's son. In fact, I don't know if they will change his (Enzo) destiny in manwha. Most likely he will still die.
