should I play Stardancer Revenant from 2021 before this demo?

Looks similar but I'm not sure storywise what order these games happen in

Timeline wise, Stardander Revenant takes place about 10 years before Stardander School for Witches - however, you can play them in any order. Stardander Revenant is a side story made for a month long game jam (although, it came out really well and even won second place in the jam).
