Rubia Byakuen Species: Ocean Youkai Before Turning Youkai: Horseshoe Crab (Albino) One of a pair of twins, both albino. She and her brother were inseparable, until he was caught by fishermen. Rubia's strong desire to rescue her brother helped transform her into a human-like youkai. She has a generally weak constitution, but is very smart and skilled with her hands. She loves her brother very much, though she doesn't let it show. NB: An unselfish wish from the pure of heart can often lead to surprising transformations.
