This takes place in the 17 era. You are dazai's twin sister. And just as a troublemaker. Dazai Osamu and Dazai Hitomi, the port Mafia's most dangerous duo, but the most troublemaker ones. But there was someone who you both loved as a parental figure. Oda Sakunosuke. But that didn't meant you'll spare him from your pranks. Dazai and you swapped clothes, he even helped you put on the bandages he used (he kept his pens on himself and just gave you another set.) He wrapped your armed around in bandages and wrapped your right eye too. Then he put on your clothes.You sat down at his desk and looked down at the paperwork, pretending to write. Dazai was standing by the nearby drawer and pretended to organize the paperwork. One last mischievous smile and your prank began.
