#i'm afraid i couldnt give as satisfactory an answer as I could because time/not really having thought too deeply about tachi

[note-boom]

@ticklinglady : Are you sure you want Tachihara to stay in the mafia? Like, yeah, I'm asking this not because I personally care about the fact that these guys are organised criminals or anything like that ahdjgjgk. I'm asking this because of the fact that Mori made Tachihara's brother go through literal torture during the war to the point of the poor guy becoming so broken that he preferred suicide over the chance to eventually return to his beloved family. That guy was the only person out of Tachihara's shitty background to genuinely care and love him, so I personally don't think it's going to be fair for Tachihara to end up working for the man, who murdered him

(Hi there!) Sorry this took me a while to answer but, once again, life.

As for wanting Tachi to stay in the mafia...I don't thiiiiink I specified actively wanting him to stay in that organisation, but I might have really just forgotten my tag rambles or not.

But to answer your question, I don't really mind either.

I see it this way, for starters.

BSD seems to have an ongoing theme of....stagnation. There is character development and progression, of course there is, but at the same time, it sometimes seems like the characters aren't moving forward. I think Kyouka and Lucy (and Dazai and Odasaku and Yosano, to an extent) are the only ones who have "moved on," so to speak. That is to say, pulled themselves out of their emotional turmoil, resolved it, and physically acted upon their restitution. But for a lot of the characters, they still seem emotionally and/or physically "stuck" in the same place they were in the past (Atsushi still believing his only worth is in to save people, most of the mafia people (though you could claim Chuuya had more of a corruption arc than restoration arc), Dazai still suicidal and a bit untethered, Kunikida and his ideals, so forth). But again, they do develop (Atsushi finding his family, the mafia characters being revealed as more human, Dazai leaving the PM was pretty significant, Kunikida HAS softened, I believe).

Tachihara had a somewhat significant arc in learning to see past his, well, past and accepting his place in the mafia that led him to believe in the ADA. He took a step forward, and learning how involved Mori was in his brother's suffering could either reel him way back in to his indecision (because he HAD made a family with the Black Lizards) or push him into more character development as he contemplates his own morality against his "orders are absolute" mentality.

It could be that he, in the end, decides that the human aspect is worth giving up his conflicted feelings over Mori given how long ago it happened (he sort of did that with Yosano). Or it could be that he simply just leaves the mafia because he can't bear the thought of it. Like, yeah, I'd feel terrible if Tachi decides to stay right where he was introduced into, but it sure would make my mind rotate him like a rotisserie chicken so much more. And if he decided to leave, taking revenge or not, I am very very curious to see what road Asagiri will take for our boy
