I decided to go about making a sort of "collage" of major points in Ms. Sophia's backstory, and on top of that chose to experiment with a different style as well.

The brief plot of Eyuna's story:
Eyuna met Leon beneath a tree in an old churchyard. The two become close until Eyuna's baby sister arrives; at which point Eyuna had to take over as "mother" while her own mom was emotionally unavailable due to the loss of her son. Three years pass, during which Leon became bitter and began seeking a way to exact his "revenge" upon the Sophia family for supposedly leaving/forgetting about him. He finds a group of humans who's goal is to take out any and all mutates in Gamma Terra, takes on a human form himself, and joins their cause waiting for the day he'd be sent to destroy Eyuna's family. That day arrives and Leon proceeds to trap Eve and her parents in their house as it is burnt to the ground while Eyuna is forced to watch it all happen. In the end, wanting Eyuna to live on and continue suffering with her grief, Leon spared her life and left her his robe which had the name Wells sewn into it. Advising her to change her last name to Wells, Leon fled the scene and returned to his group forgetting to switch back to his human form. Upon arrival, Leon is shot and killed, his identity as a mutate having been revealed by his carelessness. Unaware of Leon's death, Eyuna set off to begin her adventure, seeking the man who had betrayed her and the rest of her family.
