Hey this is just a quick thingy to like un confuse people about the story ... A Forro is a type of 'Demon or monster' that hides inside beloved toys of childeren . And in anicent times you weren't a child anymore at the age of 32 , A Forro eats the hearts/souls of heart broken people but most of the time the heart break is hard to find so they try to cause heart break insted . Usually people who are broken hearted don't care about health or how they even look so they follow what the Forro says and end up dieing .
Last chapter exampled that A forro had been after Ami , and Amu by hiding within a pink teddy bear , First it had been after Ami and suceeded and stayed with her body so she could become a ghost or demon . The forro was after Amu's heart and first made people bully her , Tadase-kun break up with her then the only person , and her mom disowning her .
Sooo if you didn't get last chapter just read this one !
