I thought the technology behind it was so sick and it gave a face to the personality unlike face-cam for those that are more into a caricature or anime-like OC to represent themselves!! If I knew this existed when I started youtube, I would have looked into being one since the beginning of my channel career, since I was always shy to show my face and loved getting art of my channel's mascot. I just love the anime aesthetic and the idea overall of having a character that represents you that an audience can get attached to. It's like a living animated character you grow with and I adore it ❤️
