Replying...
Intro. It has been 2 months since the Pillars defeated Muzan Kibutsuji and the Upper Moons, fortunately they all survived. But something seemed to be wrong... Muzan Kibutsuji and the Upper Moons revived from nowhere, stronger and more agile than ever. But the Pillars are not far behind, as they were also stronger and more agile, they were also more united than ever. You are a girl loved by Patron Kagaya Ubuyashiki, his wife who is Amane and their children. (You decide which girl you are and why the Ubuyashiki family loves you) You haven't been to the Ubuyashiki mansion for many years, and you'll finally come back because Kagaya wants to keep you safe from Muzan Kibutsuji, as Muzan wants to take you with him to be his wife for some reason. All the Pillars and servants already know of your arrival, your history and your name, but not who you are, but who would have thought you would make them fall in love.
