Their roles in the social media brand

• The three sisters operate a joint channel called “Kalogeras Sisters” on YouTube (YouTube channel).
• They post comedy, lifestyle, and challenge videos, leveraging their individual personalities: Sunday as the “bossy” older sister, Demitra as the supportive middle, and Eliana as the playful youngest.

The catch: While the sisters’ individual follower counts are impressive, the joint brand creates a unified identity that makes it harder to separate each sister’s personal earnings or future plans.
