Kento Nanami, Erwin Smith and 8 other anime deaths that left everyone in utter shock
1) Kento Nanami (Jujutsu Kaisen)

Nanami’s death was not only shocking but also emotional. As one of the most respected sorcerers, he fought valiantly, guiding Yuji Itadori and others. But the chaos of the Shibuya Incident arc sealed his fate. Wounded and exhausted, Nanami seemed to find a moment of peace, only for Mahito to snuff it out in an instant.
The abruptness of his demise, paired with Mahito’s nonchalance, made it one of those anime deaths that left fans in silence. His loss was a reminder that even the strongest warriors were powerless against the horrors of Jujutsu sorcery.
2) Erwin Smith (Attack on Titan)

Erwin’s final charge against the Beast Titan in the Return to Shiganshina Arc was a display of self-sacrifice, but it ended in devastation. Fully aware of the risks, Erwin led his soldiers into a certain death march to provide Levi with an opportunity against Zeke. A ceaseless boulder attack brought an end to his mission of solving the mystery of Titan origin and destroyed his quest, along with his life.
The irony of dying right before seeing the answers he sought left fans in shock. Viewers felt that it was one of the most heroic yet agonizing anime deaths.
3) L (Death Note)

Despite being one of the smartest minds in anime, L fell victim to Light Yagami’s plan during the Yotsuba Arc. During a battle of intelligence, L died when Rem attacked him. The moment he sensed his imminent demise, his sharp eyes softened in resignation, making his fall all the more haunting. The premeditated defeat of the world’s best detective was an agonizing sight to witness.
This anime death not only transformed the dynamic of Death Note but also left fans in shock at how easily Light manipulated those around him to achieve his goals. L's death shifted the power balance entirely in Light’s favor, proving that even the most brilliant minds were not untouchable.
4) Portgas D. Ace (One Piece)

Ace’s death could be considered one of the most heart-wrenching anime deaths of all time. Admiral Akainu stopped Luffy from saving Ace by delivering a fatal blow as Marineford Arc reached its climax. Fans of One Piece experienced deep pain when Ace moved to shield his brother at the final instant while expressing his appreciation.
His demise didn’t just mark the loss of a beloved character, it also became the turning point of the war. The grief experienced by Luffy and the Whitebeard Pirates, coupled with the brutality of Ace's death, forged a memorable tragic pinnacle in anime history.
5) Neji Hyuga (Naruto Shippuden)

Neji’s death was a true shocker, as no one expected the fan-favorite Hyuga prodigy to fall so suddenly in the Fourth Great Ninja War Arc. In order to safeguard Naruto and Hinata from annihilation by the Ten-Tails, he gave up his life without thought and remained true to his role as a shinobi. Neji's death brought emotional distress primarily to Naruto because Neji had been his former rival.
It became more heartbreaking when Neji uttered his last words about controlling his own destiny soon after he collapsed. This could be one of the shocking anime deaths, as it reinforced the reality of war and the cost of protecting comrades. It was also one of the most unforgettable moments in Naruto Shippuden.
6) Kamina (Gurren Lagann)

Kamina was the heart of Gurren Lagann, always lifting the spirits of his comrades and pushing them to believe in themselves. During a battle against the Beastmen in the Dai-Gurren Arc, Kamina suffered a sudden death which shocked all of his comrades. A fatal strike brought an end to his victory and stunned the viewers and Simon beyond belief.
Simon lost his only hope for believing in himself due to Kamina's death, which made the series veer from its optimistic tone to one filled with sadness. This was one of those anime deaths that proved how unpredictable Gurren Lagann could be, as the story took a much darker turn after Kamina’s passing.
7) Netero (Hunter x Hunter)

Chairman Netero was a powerhouse, yet his death in the Chimera Ant Arc was as swift as it was shocking. Following a battle with Meruem where he pushed his limits as a warrior, Netero made the ultimate sacrifice. The Poor Man’s Rose bomb inside his chest, activated by Netero, destroyed both him and Meruem and caused a wound to the Chimera Ant King.
His abrupt resolve to self-destruct and unexpected attack strategy made this one of the iconic anime deaths in Hunter x Hunter's history. His death diluted the Chimera Ants' threat forever because it led to their defeat and reshaped the war's direction.
8) Rengoku Kyojuro (Demon Slayer)

The battle between Rengoku and Akaza in the Mugen Train Arc showcased Rengoku's might and determination. Though he fought bravely, he succumbed to his injuries, and Tanjiro and his fellows were left heartbroken. Not having an expected farewell was, however, a reminder of the cruel demon-slaying profession.
It was one of the most painful anime deaths to witness, as his last words gave encouragement to his squad, along with a glorious acceptance of the impending death. It made Rengoku one of the most fan-favorite characters in Demon Slayer.
9) Bjorn (Vinland Saga)

Bjorn’s death came out of nowhere in the Duel Arc, as he was one of the closest allies of Askeladd. Before his passing, Askeladd offered Bjorn an honorable duel, a final act of respect between warriors. Askeladd killed Bjorn, and this moment brought Thorfinn and viewers to complete dismay.
It marked an end to an unbreakable friendship in Vinland Saga. One of the most unanticipated anime deaths, this sequence not only demonstrated the cruel nature of Viking warfare but also detailed how complicated warrior connections were during the historical time.
10) Shirou Fujimoto (Blue Exorcist)

As a father figure to Rin Okumura, Shirou was the only thing standing between him and his demonic heritage. The Opening Arc's defining moment where Satan killed Shirou turned out to be the first crucial event in Blue Exorcist and established the atmosphere of the whole series. A sudden dash of possession forced Shirou to sacrifice his life while defending Rin from danger, who could do nothing but watch in horror.
His passing shattered Rin’s world, sending him on a journey of self-discovery and struggle with his demonic powers. This was one of the brutal anime deaths, which tranformed Rin and shaped his path as he grappled with his identity and destiny.
