Omega Sisters

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.

Rio has long pink hair in twintails and light brown eyes with blue hair ribbons. Ray has short blue hair with alight blue eyes and a red bow headband.
