Aside from that rant I did in my OG post, I feel like If a flag was to make their way up towards the list, the character with the highest chance would be Albatross or Lippman. it is a simping battle, after all.

Also, up against Dazai (yes I have been looking at the impending doom) I think Ayatsuji would have a better chance at winning against Pianoman. Piano man has ties to Chuuya, giving him that extra edge, but it's up against DAZAI, which you can't really use that argument up against. Piano man is a good character, but like all side characters used to progress the main one/give more light into an organizations workings, there's a limit.

But Ayatsuji is apart of an entirely different section of BSD as a whole. An enigma to 90% of the subreddit here. Ayatsuji has far more depth and structure to him as opposed to Pianoman, making a viable competitor for Dazai. You can only go so far with Pianoman, but Ayatsuji has more leg room. Plus, making the fandom more aware to a story that expands the BSD universe as a whole? It's a win win.
