Review Detail of Seeker_Of_Quality in Mushoku Tensei: Reincarnated as the Twin Sister of Rudeus Greyrat

It's a rather good story, thought I was Initially offput by the MC's relationship with rudeus since it seemed like they were being set up for a romance, but it's actually something way weirder than that MC is a pretty fun character, she's like a mini-eris that know about rudeus's perv antics and berates him. Classic tsun with twintails. She's also a crazy freakish talent when it comes to MT swordsmanship, which I personally enjoy seeing in fics. ..But also, about 3/4 into the story, this actually becomes a honkai impact crossover? Like it turns out MC is hosting the Herrscher of Void and a bunch of other honkai characters pop up seemingly out of nowhere. They're all well integrated into the story of MT so it's not like the plot's been thrown out of the window and everyone needs to start fighting honkai monsters all of a sudden, but it's still pretty jarring.
