Open Misaka in 3D, click play or talk with her by entering the image link:
https://ero.dance/?arb=https://cdn.donmai.us/original/3b/6a/__misaka_mikoto_toaru_majutsu_no_index_and_1_more__3b6a5067d84c1043d0a898d2694b9a8a.png

How it works:
1. Open an MMD model on ero.dance and create a card out of it.
2. Upload an image here and copy the image link.
3. Enter it into the address like this: ero.dance/?arb={link_of_the_image_of_danbooru.donmai.us}
Because all the 3d data and animation is stored within the image itself.
