Ruby's Links
Ri-ri is lackadaisical in comparison to Rus, having little concern for herself or others. She deeply values their bond, but often antagonizes her brother (her way of blowing off stress). She resents him for being "perfect" in some ways, and has started to believe that she will never get "better". A different side of Ri-ri comes out around Rus, as he is her only family now.
Moppet's younger brother. Calls Moppet "Ri-ri" which is a nickname since childhood. He helps provide maintenance for Ri-ri's mechanical body, and has been doing so since they were young. they don't often see each other anymore and are rather distant, not seeing eye-to-eye on many things due to their opposite attitudes. Despite everything, Rus would do whatever he can for Ri-ri in a moment of need. He also looks up to her, and subconsciously wants to make her proud of him.
