Anime has long been a medium known for its emotional weight and bold character decisions. One trope that has persisted across many series is the “fridging” of characters, a narrative choice that often results in the sudden and dramatic death of a beloved figure. This trope not only serves to push the protagonist’s emotional development but also highlights the brutal reality that no character, regardless of their strength, is safe in an unforgiving world.
Demon Slayer: Kimetsu no Yaiba is a prime example where this trope has been used effectively to create personal stakes for its characters, particularly in the death of Kyojuro Rengoku. Known as the Flame Hashira, Rengoku’s death in the Mugen Train arc is an emotional turning point in the series, leaving a lasting impact on both the characters and the audience. Demon Slayer’s approach to fridging goes beyond the trope’s usual connotation, presenting it in a way that not only drives the plot forward but also offers a deeper exploration of the characters’ motivations.
Why Heroes Like Kyojuro Rengoku Meet Their End

In many anime, character deaths are carefully planned to either highlight the strength of an antagonist or create emotional stakes that deepen the narrative. Kyojuro Rengoku’s death is a perfect example of how the fridging trope can be used to great effect. Rather than being a random casualty, Rengoku’s demise showcases his unwavering will to remain human, even when faced with the chance of eternal life as a demon. This act of nobility is crucial in motivating Tanjiro and his team, pushing them to grow stronger in the face of overwhelming odds.
Rengoku’s heroic death also serves a larger thematic purpose: it reinforces the idea that even the most powerful figures, such as the Hashira, are not immune to the dangers posed by Muzan Kibutsuji’s demonic forces. The series is not shy about killing off characters who may seem invincible, proving that no one is truly safe. This unpredictability is what makes Demon Slayer stand out, as it keeps viewers on edge, never knowing who will be next.
The Impact of Fridging on the Story and Audience

The death of a character like Rengoku is not only tragic but also serves as a catalyst for change within the narrative. It shifts the tone of the story, creating an environment where stakes feel high and the heroes’ journey becomes even more challenging. This death, while heartbreaking, also opens the door for the growth of other characters, particularly Tanjiro, who takes on the responsibility of continuing Rengoku’s fight against the demons.
Moreover, Rengoku’s death resonates because it’s not just about his role as a powerful warrior but also about his personality. He is a lovable, charismatic figure who embodies courage and selflessness, making his loss even more impactful. The audience is not only mourning the loss of a skilled fighter but also the loss of a character who represented hope and determination. This emotional connection heightens the tragedy, creating a sense of personal loss for viewers.
Fridging in Other Anime: Heartbreaking Moments of Sacrifice

While Demon Slayer is a standout example of using the fridging trope, it is far from the only anime that utilizes this narrative device. In One Piece, the death of Portgas D. Ace serves a similar function, pushing Luffy’s emotional arc forward and solidifying his motivations for the rest of the series. Similarly, in Bleach, Kaien Shiba’s death serves to deepen Ichigo’s character development, while Jiraiya’s death in Naruto Shippuden is a turning point that pushes Naruto to evolve into a more determined hero.
These moments of fridging create a lasting emotional impact, not only for the protagonists but also for the audience. When a character is killed off, it is often done to highlight their importance within the story. Whether it’s through a noble sacrifice or a sudden, unexpected death, the consequences of these losses ripple throughout the narrative, shifting the direction of the story and adding emotional weight to every decision the characters make moving forward.
The Fridging Trope and Its Societal Implications

While fridging has proven to be a potent narrative tool in anime, it’s not without controversy. Critics of the trope argue that it can sometimes carry sexist undertones, especially when it involves the death of female characters. The term “women in refrigerators” was coined to describe a trend in comic books where women were often killed off to serve as a plot device for the male protagonist. This criticism is not exclusive to anime but extends across various forms of media, highlighting the broader societal issues that can influence storytelling.
However, the fridging trope is not inherently problematic. It’s the way in which it is used that can lead to criticism. If executed thoughtfully, a character’s death can serve a meaningful purpose within the narrative, driving character growth and advancing the plot. In fact, some stories go as far as flipping the script, featuring female characters who face the ultimate sacrifice or male characters whose deaths push the narrative in a new direction. Demon Slayer, for example, showcases Tanjiro’s entire family being fridged, not just his mother or a female character, emphasizing that anyone can become a victim of this tragic trope.
Goku and Vegeta, the iconic duo from Dragon Ball Z, have had a long-standing rivalry since their first battle in the Saiyan Saga. Despite their differences, both warriors share a common goal: to surpass their limits. However, this rivalry has often been marked by Goku’s superior strength and his natural ability to push beyond his boundaries. Their journey has taken them through countless battles, growth, and a shared pursuit of becoming stronger.
Through years of intense training and fierce competitions, Goku’s achievements in terms of power have often outshone Vegeta’s. The rivalry began with Goku’s transformation into a Super Saiyan, leaving Vegeta struggling to match him. While Goku embraced a more calculated approach to training and growth, Vegeta’s pride and relentless drive have both fueled and hindered his progress in his quest to surpass his rival.
The Saiyan Rivalry: Contrasting Paths

Vegeta’s journey has been heavily defined by his desire to outshine Goku. Though Vegeta was initially stronger than Goku in their first fight, Goku’s resilience and growth allowed him to surpass the Saiyan prince. Vegeta’s pride was severely affected when Goku transformed into a Super Saiyan on Namek, signaling a major shift in their rivalry. This moment marked the beginning of Vegeta’s obsession with proving his superiority over Goku.
Goku’s humble upbringing contrasted with Vegeta’s royal one, further intensifying their rivalry. Vegeta, born as the prince of all Saiyans, had always been taught to view others as inferior. On the other hand, Goku’s strength was built through years of training with others and learning from his mentors. Despite these differences, their shared determination to be the strongest has bound them together through every challenge, even as they strive to surpass each other.
Goku’s Consistent Edge: Overcoming Obstacles

While Vegeta’s intense training and pride have always driven him to be better, Goku’s ability to consistently push beyond his limits has kept him ahead. Even during the Cell Games Saga, Vegeta’s training failed to match Goku’s growth. Goku’s ability to master the Super Saiyan form through precise control of his energy allowed him to avoid the pitfalls Vegeta fell into with brute force training.
Despite Goku’s success, Vegeta refused to acknowledge that Goku’s approach was superior. His approach was focused on strengthening his innate Saiyan abilities, making him reluctant to learn from others. This inability to adapt and change his mindset hindered Vegeta’s progress, while Goku’s openness to evolving his methods allowed him to surpass Vegeta time and time again.
Vegeta’s Struggle: Pride vs. Progress

Vegeta’s pride has often stood in the way of his growth. Even after the Cell Saga, when Goku returned from Other World, Vegeta couldn’t help but feel inferior when he saw Goku’s advancements, including the Super Saiyan 2 and 3 forms. Despite seven years of constant training, Vegeta was still playing catch-up, and his inability to adapt his training methods to be more focused on growth prevented him from reaching his full potential.
In Dragon Ball Super, Vegeta began to make progress by accepting the help of Beerus and Whis. This acceptance of mentorship represents a crucial shift in his character development, as he realized he could not continue to grow in isolation. This newfound humility and willingness to learn from others may eventually allow him to close the gap with Goku, but it remains to be seen when he will truly surpass his rival.
