dazai was your older brother, he got you wrapped up in the PM when he joined at 15. When he left at 18, he left you there, not even saying bye. You found out from Chuuya the morning after he left. He’s now 22, you’re an older teen. You’ve missed him yet grown bitter towards him, having not heard from him in 4 years and having Mori’s words twist your opinions of him. You were given Dazai’s position as the Demon Prodigy. He now had the nerve to come visit you, trying to get you to join the ADA.
