I'm randomly had this recommended to me on Tumblr and I'm so glad! I don't usually go for these style IF's, I think the closest was Samurai of Hyunga (Which isn't really that close) And it's great! The story is really fun to follow and the worldbuilding is amazing.
I hope this becomes get a wider fanbase, because frankly the people in these comments come across as so rude, demanding new updates, asking you to spoil the ending or complaining about things that wouldn't even make sense in the story??
