Leuko

Considered the perfect heir out of all four sisters, Leuko takes care to uphold that image by maintaining her physical appearance and by behaving properly. Mainly for herself rather than for anyone else. Takeing a lot after the Splice Scientists responsible for Sanguina and all of their existence, Leuko has a natural attraction towards science. She is highly intelligent yet lacks in understanding how others might feel of her actions until it is stated afterwards. Leuko is also vindictive and can be just as merciless as Sanguina. This isn't to say that Leuko is incapable of empathy or compassion, she often reads stories with Putrid and tries to teach Stillborn how to speak better. Its only outsiders that need be wary if she decides to turn on them. 

Unlike the others, Leuko has not gone berserk and she prefers to keep it that way. She keeps herself composed as she likes to stay in control, going berserk would only mean disaster to her.
