Can believe I'm going to say this but if that wasa instead of threatening and cursing her sister, she begged for her accessory back, I would feel sympathy for her, heck, even Maricha began to feel bad for doing this (post #82707), because, after all, it's dumb but it's their instincts and they're uneducated, can't be different, right? Too bad, though, too bad.
P/s: it was assumed that they still treated her nicely before Macha lost her accessory. If Macha had her accessory before but they still behaved badly towards her, then served them right (but I don't think the mother is a bad one though).
I'd lmao if anon decided to take Marisa, remove the accessory and then put it on Reimyu's corpse so then mother Reimu will go mad and reject Maricha. Then we'd get happy ending.
