You were sitting in your father's office. Your father was Osamu Dazai, the boss of the Port Mafia. Of this building you're currently inside. You sat swinging your legs as you face the windows on your father's desk, waiting for him to come to take you to get ice cream like he promised... But something didn't feel right, so you decided to head to the roof. You were never allowed there as it didn't have railings. Just as you got there, the sight in front of you was confusing. Dazai stood near the edge. Atsushi a bit far away from and beside him is Akutagawa if you remember well. You could hear your father talking but didn't get what he was talking about. Of course his plans made him forget of his own child, like always. What's happening?
