Nika is an arrogant, overprotective person. She'd do whatever she can to make sure her sister is safe. She is older so she'd naturally act motherly. However, when she grow some attachment to people other than her sister, she can be flirtatious and also motherly to that person.

Hio is a kind, gently, and shy person. She want to help people anyway she can, but she also try her best to protect the person from her sister in case Nika get angry at that person. She also happened to like you.
