I Have A New Headcanon That The Reason Why Tachihara Stabbed Kenji With The Sword Back In Season Four

You know, for as much as bsd has spiraled, I don't think Fyodor's motivations have really changed all that much since we first met him.

He's always hated ability users. A fact which I think a lot of people tend to forget is that most regular people don't know that much about them, except that they were part of the war. They know they exist, but in contexts like the Port Mafia and vaguely aware of the Agency's existence. They're not people who are liked, they have to be watched by the government, and Fyodor's always hated them.

He wants to rid the world of ability users, because he believes they are a sin (despite him being one himself). We don't know why, and I don't want that Tragic Backstory™ because I'm happy hating him as he his now, but that's been the case ever since he tried to have the Agency and Mafia defeat each other. Ever since the movie where he was willing to team up and cause a Gifted Genocide via Gifted Suicide. Also, he's kinda right about Fukuchi's plan being flawed like...yeah, world domination has never worked out well in the past. So him wanting a war against all Gifteds and manipulating Fukuchi to do it actually makes tons of sense, considering what we know about him. He thinks that peace will come as soon as the Gifteds are done with.

beast dazai is considered a tragic character for all the obvious reasons: carried the weight of the memories of his other selves and using that knowledge to save oda from his fate even if it meant dying/killing himself in the end. This sympathetic narrative allows you to ignore the utter selfishness and immaturity of beast dazai and how he runs away from grief and pain, and I mean this in the best way possible.

The real tragedy of beast is that unlike all the other dazais, beast dazai never got the chance to meet and know oda, thence allowing him a new perspective to grow. In The day I picked up Dazai , dazai shows personal growth by the end of the novel, hence why he respects oda a lot. He is treated as a human being who still doesn't know much, and that brings comfort to someone deemed a demon prodigy. In side b of the same novel, beast dazai makes an effort to not know or bond with oda; yes this is because he wanted to ensure his survival by steering him away from the port mafia, but that event is what fundamentally changed dazai- gave him a better understanding of his own humanity.

Despite having all that knowledge of his other selves, of how each universe's timeline will play out, beast dazai didn't seem to grasp that it is grief that allowed the other dazai to grow and be a better person. He didn't understand that in the end, it is the time he (the other dazai) spent with oda that made living worthwhile, not his life. His state of living, the state of perfection in beast dazai's eyes, will still cause him more suffering than the act of losing a good friend.

Because if he had only wanted him to live, then he wouldn't have been so shocked when oda refused to indulge in a friendly conversation, not when he clearly went out of his way to antagonize himself in oda's eyes in tdipud. It's because the realization hit him: he wanted his time with oda to not be cut short.

Having memories of another oda is clearly not enough, he needed his own intimate friendship with his own oda. But with this elaborate plan and his reaction to being rejected, it's clear that beast dazai was trying to avoid pain. He could not accept the grief and pain of loss that he's seen and felt in his other selves, ignoring what came after: growth and satisfaction of ever having oda in their lives at all.

Pain is inherently human and by ignoring and rejecting it, beast dazai rejects his own humanity. Or runs away from it, because it catches up to him regardless. He still ignores it throughout the rest of the story, especially in other characters.

Beast dazai, as we all know, eventually takes his own life. While there is a reason as to why he did it, but it was still part of his plan from the beginning. Meaning, he knew this near fruitless pursuit would still have him unable to handle grief. It's an inherently selfish goal with an inherently selfish way out under the guise of "leaving the rest in atsushi and akutagawa's hands"

(Note: I do not mean in any way that suicide is selfish, but rather the narrative and character of dazai in beast alludes to this. Both concepts can co-exist in a fictional setting)

Despite seemingly helping other characters, beast dazai also trampled on both akutagawa and atsushi's self worth. This made them easier to manipulate for his grand plan, but ignores the damage he's done to them and other characters after his death.

For akutagawa it is the loss of his sister and convincing him of his monstrosity due to Dazai's meddling. For atsushi, someone he conditioned into severe fear and dependency on him, was left alone watching the person he cared so much for fall from the building. And yes, he left him in mori's care afterwards, but dazai should know more than anyone the damage the death of a loved one has, unless it doesn't apply to him.

In the epilogue, mori openly mourns dazai's death along with atsushi. Due to being free of his rigid responsibility as the pm boss, he had the liberty of finally being the caretaker he's always wanted to be but at the cost of the person he considered his son (in comparing dazai to atsushi, who he then calls his son + all the other stances where mori treated dazai like a son etc)

The thing that beast dazai, or dazai in general, tends to not fully understand or accept, is that he is also loved, and his death will cause others pain as well. I am by no means saying he should've thought of others before dying, but it is the lives of others that dazai from the main manga also cherishes after oda's death. Beast dazai made it his entire life goal to essentially protect oda, realize its not the only thing he's wanted from him and gave his raison d'etre a flimsy excuse of meaning in life. It's inherently selfish.

Selfishness is a common theme in bsd, and beast dazai fits right in. Atsushi's selfish desire to save people to give himself a justification to be alive, Sigma's inherently selfish nature of self preservation and identity and so on.

I've probably ranted for much longer than anticipated, but the point is: beast dazai's purpose is a selfish desire to escape pain and loss when it's crucial to the human experience. Dazai in the main manga seems to grasp this much better than beast dazai, it's something the latter is "missing", refusing to grow out of his selfishness and it makes his character more of a cautionary tale.

Bsd is really just a blend of every genre like you got detectives powers mystery guns violence trauma (lots and lots of trauma) war "rivalry" mafia book vampires and one time a character fought a dragon.

Literally. The second the finale aired, the whole arc suddenly turned from tragedy to comedy. And suddenly, Chuuya was very justified for shooting Dazai an extra few times.

EXTREMELY funny Chuuya frame in retrospect

Chuuya can't tie a tie. This is canon, you won't convince me otherwise.

He grew up on the streets. When he was sixteen, he wore the usual Mafia getup, but no tie. In his usual outfit, he wears a bolo tie.

Therefore, it is scientifically proven that Chuuya cannot, in fact, tie a tie.

It's such an underrated little detail that Atsushi, in fact, did not want to join the Agency, because he thought the job was too crazy and violent for him, and he firmly believed every single one of them was nuts (which he's not wrong). Dazai simply manipulated convinced him to join by pointing out the fact that Atsushi didn't really have money or friends. So he was stuck with the weirdos.

Like, he seriously just wants a paycheck and chazuke. Oh sure, he found a family in the ADA, but I'm sure he thinks he's the only sane one there.

Happy birthday best hat man (ver2025) 🎩✨🥳🥳

tbh i think that scene is less about atsushi “learning the truth abt dazai” and much more about him finally being able to acknowledge how much of himself he sees in akutagawa without the mental block of his warped perception of dazai. and even then i don’t see this seriously impacting atsushi’s relationship with dazai like this is about his relationship with aku

FOUND FAMILY COMMITING WAR CRIMES FOR EACH OTHER.

Seriously, how are there people who don't see them as a found family? They're literally the most wholesome part of the series. They better be reunited soon, and I want an entire episode dedicated to the afterparty.

"Kunikida is alive. If he died, there's no way I wouldn't have sensed it. Not just Kunikida either. As long as at least one agency member remains alive... They will never stop resisting. This battle will be won by my team."
