Okay, I skipped through Pancake Gehenna on JP, finally read it.

It's NOT GOOD
However it isn't aggressively bad either. I think there are 3 major flaws in it. First is that it keeps harping on "Hyuck, that's Gehenna for you!", Second is that this premise was a side story in Hina anniversary making it kinda bizarre that everyone is only like "that sounds familiar" not "not this shit again", and Third is that it's a Juri event and Juri hardly matters in it. I think it would've been nice to try to half-explain WHY she's able to cook well now? It was just random, even though in Momotalks her cursed fingers couldn't even be allowed to touch a pot of boiling water lest it diabolically spoil. It was nice that she showed off her heart, I'm happy that she has improved, but it's annoying there's not even a half-explanation.
Fuuka sucks in this event, dedicated tsukommi and her only good part was tossing Pan-pan in the garbage.
Ako was delightful, especially because she wasn't constantly talking about "Gehenna, amirite?" and I'm not even a "Gehenna complainer" they just really overdo that joke. An event that could've used show don't tell, more Juri, and a little more confidence. It kinda reads like an event written for new players instead of one assuming you know about Blue Archive. Even Hina Anniversary wasn't so "repetitive".

I'm glad Iori wasn't a complete joke in the event and that, in general, Iori has been given some shine in 2025 (I did read the Highlander event and new Trinity Summer so I know she comes back and is great again in those)
I also skipped the baseball event on JP, but I'm less worried about that one since I tend to think Millennium events are quite funny.
