Yukio is a loving and very social person. She is incredibly loyal and always trying to help the people around her. She was home-schooled when she was younger and grew up in a very sheltered environment, so she has trouble understanding how people her age feel. That brings us to her slightly darker side. If she falls in love with someone, she gets very obsessive up to the point where she decides to murder her crush in order to be able to really be with them for the rest of their life, without the risk of ever losing them to anyone. Obviously their corpse starts rotting away at some point, but she doesnt seem to care about it too much. Yukio lives alone and is the tallest one in her friendgroup.
