Sorry, I keep double, triple posting, whatever, but I just had another thought

If that truly is Sariel on the cover, she might actually be the stage 5 boss

This is just more wild speculation, but what if the stage 6 boss is another PC-98 character? Someone who resembles Sariel a lot, same long white hair, six wings, only hers look a bit different?

What if the stage 6 boss is actually Shinki?

I always wondered why they look so similar: maybe they're actually sisters, and not just sisters, but identical twins

I don't think ZUN has been planning this far ahead for this long, he probably just reused Sariel's design for her, but if this is true and he really has been planning this out this whole time I'll be amazed
