Continuation or more of a clean-up of my previous post, with less imagery.
One possible reason for Akutagawa's actions could be that he has come to see value in a life beyond his own. In Beast, we saw him attempting to teach those who killed his friends the value of life through killing them. However, in doing so, he lost his own way and failed to recognize that he never truly demonstrated the value of his sister’s life—or even his own—due to his recklessness. By the time he realized this, it was too late and took a lot of...well beast's drama to make him realize that, and ultimately the way he thinks and the psychology used in beast is one of the best portrayals of akutagawa as a character.
In the current timeline, of the mainline manga, to do with the above image, the answer may lie in the idea that, after everything, he has come to see value in Atsushi’s life: a life other than his own, someone similar yet fundamentally different—a true counterpart, the other side of the coin.
This could be seen as a way for Akutagawa to, in a sense, save himself or his past self. Unlike when he expressed being glad for Kyouka, this time, it is different. Here, his actions seem to reflect a profound shift, one where he acknowledges the importance of another’s survival beyond his own goals and desires.
Dazai himself stated that he knew why Akutagawa would save Atsushi. Throughout the series, it has been evident how much the two have grown from their dynamic and how their relationship has evolved. Beast provided further insight into how they might function even as friends. Their role as the successful Soukoku is something particularly compelling. Looking at previous partnerships—Mori and Fukuzawa, who stand in stark contrast and could never work together; Dazai and Chuuya, who were forced into collaboration despite their differences but remained reliable comrades when it counted—we see how these pairings reflect their respective dynamics. In contrast, Akutagawa and Atsushi embody the Yin-Yang balance. Their designs alone reinforce this contrast, illustrating how they either complement or challenge each other. While SSKK (Shin-Soukoku) may not be the best term for their unique balance, their development is undeniably profound.
From the very beginning, Akutagawa and Atsushi’s interactions have been charged with conflict, misunderstanding, and eventual growth. Akutagawa was shaped by Dazai’s ruthless mentorship, learning to equate strength with worth and mercilessness with survival. Atsushi, on the other hand, struggled with deep-seated self-loathing instilled by the orphanage director’s abuse, believing he was unworthy of love or existence. Their clashes stemmed from these core beliefs—Akutagawa saw Atsushi as a weakling unfit to be recognized by Dazai, while Atsushi saw Akutagawa as a monster incapable of redemption. However, their battles forced them to confront these misconceptions. Over time, they each began to understand that their value was not defined by Dazai’s recognition, nor by how they were treated in the past. Instead, their growth came from the challenges they faced together.
Many theories surround Akutagawa’s memory loss, but here, he is undeniably fulfilling the role of a protector—mirroring the ideals of Knight Akutagawa. Looking back, he has always had a protective streak, as seen with his deceased friends in the slums. Furthermore, Rashomon is not only an offensive ability but also a defensive one, reflecting his dual nature—capable of shielding both himself and others. This aligns with his evolution as a character, one who has always been a guardian in his own way, even if it wasn’t always apparent. Additionally, Rashomon’s adaptability is a direct parallel to Akutagawa himself; while he initially wielded it purely as a weapon of destruction, as it is shown to be, to devour everything in its way. But it also protects him with its shielding and defensive capabilities, and a knight both fights and defends for others - but besides that and making any connections there I would have to say, we all could already see his ability comes from - his coat, his clothes, his "protection" which he feels to vulnerable without (reason why he doesn't like baths.) And not to mention the moment where Dazai shot him 3 times for failing a mission and Rashomon automatically acted to defend him. His character is built on themes of survival, how the environment shaped him etc. afterall.
Akutagawa’s death had a significant impact on Atsushi, not just from a shipping perspective, but from a purely narrative and analytical standpoint. This moment is one of the most defining in the series. It also makes complete sense that Akutagawa would regain some—or even all—of his memories afterward. He had spent so long fixated on killing Atsushi, with their agreement hinging on his ability to refrain from taking lives for six months before their ultimate confrontation. This duel, if it still occurs, could parallel their fight in Beast in a meaningful way.
This act of self-sacrifice marks a crucial turning point for Akutagawa. His life had been centered on pursuing his wants, achieving his goals—many of which were rooted in selfishness. This mirrors Atsushi in some ways, especially since they both do an action (killing/getting stronger or saving lives) to give their life meaning or for feeling accepted into the world, which are both endless paths which they both need self-growth on to get to a better point (also I believe akutagawa could be going the Odasaku route which I am excited for but lets not get too into that.)
However, for the first time, this was an entirely selfless act. He wasn’t seeking personal validation or a step toward his own ambitions; he was protecting someone. Not just someone, but someone he had deemed worthy of being saved. Someone who deserved to live because he had finally come to understand, at least somewhat after this, the value of others’ lives truly, instead of from a survival kind of "the weak die, die and make way for others" which he grew up with not just in the mafia but in the slums too where it was said his lungs would burn and the people "above" would "look down" on them but never truly acknowledge their existence, its sad to think even after Dazai found him he never really showed akutagawa that he acknowledges his strength or how far he has gone really, but this itself has many theories and arguments over reasons and potentially the plot moving forward with their characters and Dazai's reasonings. Anyways, this is why Akutagawa "woke up" when Atsushi sacrificed himself, repeating the same words Akutagawa once did. It was a moment of profound narrative symmetry, one that encapsulates Akutagawa’s arc.
A notable mention here is 55 Minutes, which further supports the idea of Akutagawa’s memory resilience. Despite dying in flames, after time was reversed, he retained memories of events that theoretically never happened. He remembered the exact time of the disaster and even made a point to check on Higuchi around that same time. This suggests that certain experiences impact him so deeply that they imprint on his consciousness, even when they logically shouldn’t. A similar phenomenon can be observed with Vampire Akutagawa. Despite being under vampiric control, he retained fragments of his consciousness—spared Aya, responded to Atsushi’s words, and, most significantly, kept his promise. Vampirism should have rendered him a mindless tool, yet even then, his core principles remained intact.
This aligns with a recurring theme in Akutagawa’s character: his defiance against being controlled. He has always been a "dog" to the Mafia, yet one that could never be fully tamed. His ability to retain memories and emotions, even under extreme circumstances, reinforces his complexity as a character. This trait plays a pivotal role in his development, ultimately shaping his choices and his final, selfless decision to protect Atsushi. And of course, all of this ties back to Dazai…
Ahem, his eyes. Besides being glorious and magnificent, I've been thinking and spoke to a friend recently on this. It seems his eyes only turn white when he is scared, vulnerable, or determined in the right direction (when he said "understood" to bram there was a light in his eyes.) And we all know Harukawa's genius and interesting way of making eyes go from dark to light showing their development or a change in their views too. The darkness showing how "tainted" they are or "dark" themselves. To which Kyouka used to have dark eyes that turned light (actually kind of grey) and Dazai's is still black. Akutagawa's has also been black/dark a lot of the time, and usually when he is shocked we see his dark/black eyes shrink in surprise unlike this moment where we see the light in it and his pupil for once. So its an important moment, especially since this is where he iss regaining some if not all of his memories. Although we still need clearance on what happened to him which would be shown in the next chapters after the whole S03 4D universe lore is done dropping completely, or possibly after the Amenogozen battle.
Thats all for now from The Akutagawa Fan, Charkoala, Caldera whichever name or title works.
