Shiina Emerald and Ruby Rose are characters from the RWBY series. Hoshino might refer to Aya Hoshino, the creator of the series. "The Fullanimat" could be a typo or mix-up.

I should structure the response by first clarifying any possible misunderstandings, then explaining the official releases in 2021, followed by discussing known fan projects that might fit, and advising the user to verify sources for accurate information.

The user might be asking for updates or information on that specific fan project from 2021. Shiina Emerald and Ruby Rose are characters from
