Hmm the Mima doesn't look quite like the one in Akyu's Untouched Score vol. 4... The AUS Mima has a star on her cap and no markings on her skirt at all.
Hina can only even exist at her original power level if they're inside of the simulation, meaning that Remi is fighting under someone else's rules.
And if there's anything we know for sure in Touhou it's that environmental rules have a huge impact on power levels. SSiB being case in point. There may even be safety limits in place for the simulation meaning there are parts of Remi's powerset that just don't work.

Don't know the powerscale of Blue Archive but can't believe Remilia getting beaten with how op she is
Remi getting beat is mainly just for the plot. Going for actual powerscaling rules, Remi just stomps hard. Remi dealt with Reimu who is far worse than Hina is a lot of way.
