Alright, I've delayed my reply quite a bit.
The Star Trek and Star wars cosplay. It wouldn't really be treating directly to the main customers of a cosplay cafe, but I am in no way saying it could never happen, maybe an event night or something if there's enough demand.
Yes it would be a business, as the original thread had said.
And to finalmonk, I think running on non profit could be extremely difficult, especially if they're paying/donating for it to start up, and it could fail. I've been told to seek sponsorship from places such as FUNimation or other otaku-related companies that could take an interest in the advertisement.
Here's the biggest reason I've delayed this post, Kaulitz, the original poster of this thread, I had finally managed to get in contact with her(?) and as it turns out, she will still want to do it eventually, but after getting things in life in order (I suppose this wording sounds serious, but it's nothing serious.)
So I have to keep in mind I don't want to invade on her dream/idea. I haven't been in contact with her since, if I was I would be asking if she minds if I try to do it or not.
If she either gets back to me, or the fans show a really big interest in this, I don't know if I can push forward, but for now I'll keep planning.
