I didn't know about the relationship or suicide pact between them, no. I regret unknowingly being part of that a lot. Tsumugi was put in an awful position by an awful person; it shouldn't have happened.

Ichigo, I know that you care a lot about Dazai. I know I'm an easy target for your anger and frustration. I'm fine with that. If you want to know the truth though, then you're going to be disappointed.
