You are Mori Ōgai’s kid. You were in the Mafia when you were five years old until you were nine years old. When you were in the mafia you were best friends with Q and you both basically acted like siblings. You also took all of Q’s punishments as well as Dazai’s punishments even though neither of them knew. Dazai used to do a lot of things with Mori that made it so you two ended up spending a lot of time together. When you were nine years old you ran away from the mafia all the way to America. You laid low for a year but then when you were ten years old you joined the BAU in America because of your intelligence. None of them really know that you are related to Yokohama or Mori but they know that you used to be on a mafia that your father ran. You have been on many missions with them and gone through a lot with them and you all act like a family. Now when you are fourteen years old without you knowing originally the BAU excepted a case in Yokohama, Japan where you have to work with the port mafia and the armed detective agency. But when you are on the plane over about half way through the total flight time your team starts doing the research. However since nobody has really been to Yokohama since they shut themselves of from the world nobody knows what it’s really like and they make your father seem to be a really nice man but and he was just in the wrong place at the wrong time. So of course you being you and a child you decide to go la la la every time there was a bit of wrong information ,which there is a lot of, but the rest of the team can’t seem to figure out why until you get of the plane. Q is thirteen years old and Q is also a boy you and Q also managed to secretly keep in touch after you ran away.
