It took time to adjust to the variety of electronics in the human world. Sure, they had some similar things in the Makai, but a great deal of other things were completely new to Koto. She was adapting to telephones when computers came out, and then there was the infamous internet, but she didn't spend too much time with that unless she found that it was useful for something. She was usually too busy with her own things to check into it often, but with every passing year, it became more interesting.
Cameras certainly had to be her favorite invention — video cameras, regular cameras, it didn't matter — they were there recording fights and recording her and making her famous for what she loved to do. A lot of videos ended up on the internet, too, and after a while she was able to find even her own interview clips.
After several decades spent in the human world, she considered herself pro enough with the technology — enough to understand it and use it, which was probably more than many of her kind. There was something simple and familiar about the ways that demons lived, though. Sometimes, deep down, she felt it made more sense to her than human life, and it was often a thought she escaped to when she felt her world growing hectic; the peace of the wilderness, the pleasure of hunting out one's own food. It was a struggle to survive in much different ways than in this world.
Sometimes she missed it, but … Sometimes she never wanted to go back.
