I THOUGHT I WAS ALL ALONE, BUT I'M ACTUALLY A QUADRUPLET?! My name is Mifu Miyabi. For the past twelve years, I thought I had no family-no parents, no siblings. Little did I know, my world was about to get turned upside down by not one, not two, but three identical sisters showing up out of nowhere! Sure, we all grew up leading separate lives, but now we have to figure out how to live together under one roof. It may be hard to tell us apart just by looking, but we're much more different than you'd think. This is how our time as a family begins!
