Leon Links, son of James Links and Dr. Rachel Links, has a sister named Noel Links. Before the series' events, he worked as a programmer for a prominent firm. Leon harbors deep resentment toward his father due to family problems stemming from James' abandonment. This bitterness shapes Leon as somewhat cowardly and less self-assured compared to Noel. His strained family bonds, particularly the estrangement from his father, anchor his background.
