Uncover the deuteragonist role of Shin Asakura in Sakamoto Days. Find out how he shapes the narrative and supports Sakamoto.

Sakamoto Days has slowly gained popularity over time. It has a unique storyline compared to the usual shonen plotline. Here, our protagonist, Taro Sakamoto, a legendary hitman, leaves his previous lifestyle to live peacefully with the woman he loves. This series has introduced a lot of characters who either support Sakamoto or try to get him back as a hitman. Among them, Shin Asakura stands out. This prompts us to ask: Does Shin qualify as the deuteragonist of Sakamoto Days?
In this article, we will explore Shin Asakura’s significance in the story by discussing his relationship with Sakamoto, his character growth, his involvement in plot development, and his personal motivations.
Is Shin Asakura the Deuteragonist

The deuteragonist is a character who is supposed to be the second most important character in a story, where they support the main character, helping them grow and allowing the story to develop further. Shin Asakura is initially introduced as an assassin with the ability to read minds due to his clairvoyance powers. His immediate partnership with Sakamoto sets him apart from other supporting characters.
Unlike other characters, Shin has a very important role. He has been more than just common support to Sakamoto. He has his own arc where he undergoes significant growth in skill and emotional depth, making him more than just comic relief. His importance in the story and close bond with the protagonist strongly support his role as the deuteragonist.
Shin’s Relationship with Sakamoto

Shin sees Sakamoto as his mentor, and he is a humble apprentice. But there is a deeper layer to it, as both of them bond through mutual respect and camaraderie. Initially, when Shin was tasked with assassinating Sakamoto, he was surprised to see him so out of shape. To his surprise, Sakamoto was not rusty but a very deadly opponent to have. This realization reignites Shin’s admiration for his boss and his willingness to learn from him.
Shin’s ability to understand Sakamoto’s thoughts through his clairvoyance provides a unique insight into the former assassin’s character, allowing readers to see beyond his stoic exterior. The dynamic of their relationship grows as Shin uses his power to protect Sakamoto. Meanwhile, Sakamoto’s laid-back behavior gives Shin some breathing room. In turn, they balance each other, ensuring their missions don’t end up as failures.
He also bridges the gap between the past and present. This provides perspective on Sakamoto, helping us understand him on a deeper level. This makes Shin an even more significant character.
Growth and Development

One of the strongest arguments for Shin being the deuteragonist is his character development. In this series, we see that he has the skills to be a good assassin, but due to his inexperience, he is not as legendary as Sakamoto. He makes up for it by facing numerous trials that continuously test his abilities and resolve. After every difficult challenge he overcomes, he grows into his potential.
An important point in his growth is when he realizes he relies too much on his telepathic ability and does not train enough in his physical abilities, combat techniques, and strategic thinking. Once this realization hits, he makes sure to work on it.
It is also important to note that his development isn’t limited to combat skills. Shin also undergoes emotional and psychological growth. Initially, he is hesitant about killing, but he gradually learns to navigate the moral complexities of the assassin world and becomes mentally strong enough to make difficult decisions by himself.
Shin’s Role in the Story’s Conflicts

Shin seems to fit the criteria of a deuteragonist well, as he plays a major role in the central conflicts of the story. Whether it’s facing off against strong assassins, uncovering hidden threats, or supporting Sakamoto in life-or-death situations, Shin always finds himself in the middle of the action.
One of the most important aspects of Shin’s involvement in fights is that he often has to overcome personal limitations. While Sakamoto is nearly invincible with his skills, Shin often finds himself at a disadvantage. However, rather than always relying on Sakamoto to save him, he actively works to improve himself.
Shin’s telepathic ability also gives him a strategic edge. He can anticipate enemy movements and relay critical information to Sakamoto and their allies. This makes him an indispensable part of the team, further proving his significance in the narrative.
Rivalries and Personal Motivations

Personal motivations and rivalries are two qualities that drive a character arc. Shin’s past as an assassin and his decision to leave that life behind create interesting conflicts for him. Unlike Sakamoto, who has fully embraced his peaceful life, Shin struggles with his role in the world of assassins.
Even when he was sent to assassinate Sakamoto, we see his internal dialogue where he kept questioning himself. We knew from the start that he was going to be different. Also, after he found his place by being connected to Sakamoto, it was as if both their lives heavily influenced each other—facing the past and working towards a better future while overcoming challenges together.
His rivalry with other characters also adds depth to his story. Throughout the series, Shin encounters various skilled assassins who challenge him both physically and mentally. These rivalries push him to grow stronger and redefine his purpose. Moreover, the series slowly reveals Shin’s past story, giving clarity about him and his motivation. His experiences in life shape his outlook, and we understand his journey of self-discovery. This complex subplot adds another layer to his character, proving again that he is more than just a support character.
Conclusion
In conclusion, we can say that based on his role in the story, his relationship with Sakamoto, his character growth, and his involvement in conflicts, Shin Asakura fits the definition of a deuteragonist. While Sakamoto Days features multiple important characters, Shin consistently stands out as the second-most significant figure in the series. Thus, it is fair to conclude that Shin Asakura is indeed the deuteragonist of Sakamoto Days.
