Second one on the list, Kochō (the queen) Shinobu. Her kagune is a Koukaku just like Ryoko Fueguchi's kagune.
I added some small butterflies as well just for the aesthetic, and I made hers a Koukaku just because I can and she'll look amazing with it.
Took me an hour and 40 minutes, so I guess it doesn't took as long as I thought it'll be.
