[Scarlet and Old MacDonald's bloodline weren't pure and had a mutation. Due to this, they couldn't use the blood fruit sacrificed from the Human Progenitor and Wolf Progenitor.]
[Although you could change their bloodline to the non-mutant version, you never did that since their bloodline's mutation was a positive change.]
[For example, Old MacDonald's fairy tale path allowed him to have better affinity and talent for his role as a rancher and farmer. As for Scarlet, her being a moon-attributed werewolf meant that she had a higher affinity and talent towards the comprehension of the Moon Principle.]
[You've also informed them that if they wanted to change their race to the non-mutant version, and it seemed that both Old MacDonald and Scarlet were more than satisfied with their mutated bloodline.]
[Having already given them the option, you no longer pursued that matter and respected their decision.]
