If you're specifically interested in story, Fate/Grand Order is a strong recommendation. It's an absolutely awful game by every other metric, summon rates are terrible and the pity system is a slap in the face, summoning currency runs out fast and comes back slow, gameplay is ridiculously dull and repetitive and almost completely unskippable, and it just really doesn't have any respect for your time whatsoever. I've been playing for close to a year and I couldn't recommend it more highly~

That said, based on your post, you've almost certainly at least tried it, but I don't think there are any others I could recommend at the moment...except maybe Honkai Star Rail, which you specifically mentioned, so that's out!
