>>49193379The artists don't hand their IPs to Nijisanji. They draw a model that is owned by Anycolor in different outfits. Imagine there was a contest where you can submit Pikachu in different outfits to Nintendo. Someone draws Pikachu with a hat. Now that person claims he invented Pikachu with a hat and throws a tantrum on Twitter.
Selen could be drawn in an idol outfit. Now that artist forever owns the right on Selen in an idol outfit.
It is just common sense for the company to play it as safe as they can. If you think you should own any rights to a Selen outfit, your brain is busted. And I say this as someone who knows artists that make a living selling fan art.
