I am barely remembering this exist anymore XD But glad to hear its a 2d animation.
That's good to hear, although I am still surprised there is not a single image so far, even if its just a background/setting image.
I am fine with removing the cast pages and linking them to the other wiki. I have never been a fan of cast/crew pages, but didn't want to enforce such rule when the wiki started as people were making those pages and seemed passionate about it. Additionally there was nothing else to do at that time.
I have been working on anime wikis for a long time and anime wikis essentially never have voice actor pages. Reasons are simple. Most of the time its a very short basic info as we don't have information about lesser known people. Often the info is just copy-pasted from somewhere. And third: the engagement in maintaining the pages is too big, going out of the scope of the wiki and even beyond after the series end. That's because those articles need to always be updated with what new role the actor did even if its been 10 years since the show ended.
