Omega Sisters

The Omega Sisters (おめがシスターズ [Ω Sisters]) are a pair of twin female Japanese Virtual YouTubers, Rio (pink hair) and Ray (blue hair).

Personality
Rio and Ray are friendly, cheerful and good singers.

Ray is often seen as a heavy otaku, always talking about her hobbies such as Yu-gi-oh, gunpla, tabletop, etc.. When it comes to her hobbies, she always goes overboard to the point that Rio often complains in their videos.

Rio is the airhead, often having no idea what Ray is talking about when it is related to her hobbies. When there is a chance, she often tries to make jokes.
