i want to find kisaragisakuya video anyone know where is he..??
Here is a post about some old creators who left and later returned under new names. Hope it helps.
Pretty sure their name is Viscous Space now. Almost all of their videos are on their patreon now so you'll have to go there for them or search the web for pirated videos.
I'll pm you a link to the iwara forum post that has the old creators with new names on it.
