I guess... The worldline where Kaede stays the girlfriend is over. Author really cooked up something alright. And with an ending like this... I assume the LN was well whatever it was.
Story had alot of potential but I guess in the end the one she loved was Tsubaki , I guess if there wasn't an axe we would have gotten a deepdive as to why the double fell for the best friend but oh well.
This axe is the sharpest I've ever seen. Like a God from the Machine came down to explain the super natural, absolve all the problems, and fucked off with a good ending that is underserved given what happened a day ago from a story perspective.
