When they were children, Leah was irritated at Rachel's silent personality and her stubborn attachment to Leah's dolls and things. Once, when she became angered by Rachel, Leah pushed her and unintentionally made her fall down their home stairs, disabling Rachel spine down and putting her in a comatose state. After their father's successful attempt of reviving Rachel by injecting her with P73 Bias Factor, Leah started to be supporting of the now more talkative Rachel and told her that she would give her everything she had as part of her make-up to her sister. Years later, both sisters became Fenrir scientists with sponsorship from their father for Leah's God Arc Soldier research project. Rachel is confronted by their father on her use of orphaned children for her experiments and threatens her with a complaint to Fenrir in order to stop her experiments. However, Rachel has their father killed by her God Arc Soldier prototype leaving a burning car wreckage outside their house to which Leah breaks down in regret and apologizes again to Rachel repeatedly for making her become the person she is now. Leah would continue to support Rachel while on the Friar even with the full team of Blood was present until she finally could not bear supporting Rachel and her experiments and escaped. She sent out a rescue signal and was picked up by Blood unit, which had been reassigned to the main branch, and told Blood of both of their pasts in a last attempt to stop Rachel's human experiments.

- Protagonist (God Eater 2) - Supportive of their initial efforts as a member of Blood, Leah also entrusts them with helping Ciel grow as a person, telling them of how she and Julius never really bonded when they met at the Magnolia Compass. After she runs away from the Friar, the protagonist and the remaining members of Blood find her at the Dead City at Dawn. They take her back to Anagura, where she's kept in the infirmary so she could rest, and as she recovers, she tells them, and Ciel, of her past, and of her conflicted relationship with Rachel. She lays her hopes on them, and on the chance that they will stop her sister's experiments, with this gesture.
