Calliope Mori is a professional singer-songwriter who has released an EP that has reached number one on the US and Japan hip-hop charts, as well as the top five albums overall. She has a very cool and instantly appreciable character design, with her new outfit epitomising that aspect of her. She has 400,000 more subscribers than Kiara. She's very well respected by the Japanese, who think she is the epitome of a "cool westerner", to the level where she's actually intimidating to them. She streamed during JP primetime at the end of Golden Week.
Kiara is an orange, shrill bird with two hats. She is streaming at offpeak hours for almost every relevant timezone.
