Solo Leveling has dominated discussions this winter season, with some claiming it’s overrated, while others argue it’s a standout anime. Despite mixed opinions, the anime adaptation has proven itself worthy, showcasing A-1 Pictures’ breathtaking animation. The battles, approved by manhwa readers, do justice to the popular series and highlight the urban fantasy's undeniable appeal. Solo Leveling's adaptation has rightfully earned the attention it deserves, captivating fans with its intense action.

However, it's not just the animation that draws viewers in, but the unique character of Sung Jinwoo. Unlike typical shōnen protagonists who often show empathy for both the innocent and those who’ve harmed them, Jinwoo fights solely to win. Heroes like Naruto Uzumaki, Tanjiro Kamado, and Gon Freecss are normally depicted to fight with comion. Still, Jinwoo is determined in his mission to protect those who truly deserve it, making him stand out in the world of shōnen protagonists.

Sung Jinwoo Suffered and Endured as an E-Rank

The Weakest Hunter Turned the Strongest

Sung Jinwoo from Solo Leveling undergoes a dramatic transformation from season 1 to season 2, so much so that those unfamiliar with him might mistake his two appearances as completely different characters. Like many shōnen protagonists, Jinwoo had a difficult start. He faced struggles as a son and lowly hunter, working tirelessly to provide for his younger sister and their mother's medical bills. Despite being mocked for his weaknesses, he took on any dungeon quest available, swallowing his pride and keeping his head low.

In season 1 episode #1, Jinwoo’s infamous reputation as "The Weakest Hunter of All Mankind" made him a well-known figure. While others recognized him, they mocked him behind his back, assuming his dungeon quests would be nothing but a failure. Despite the ridicule, Jinwoo stayed calm, maintaining his kindness while battling feelings of insecurity. His self-doubt only grew as others around him seemed more capable, but he remained determined to prove himself, even if it meant being used as a sacrificial pawn in dangerous quests.

Being an S-rank today doesn't erase the suffering and lack of self-worth that Jinwoo once felt.

This mentality led him to the fateful Double Dungeon quest in season 2 episode #2, where Jinwoo was left behind to fend for himself. Understanding that he was the weakest, he accepted his role as the sacrificial lamb. However, after a near-death experience, Jinwoo realized his worth and immediately regretted his decision. This turning point, while offering him a once-in-a-lifetime opportunity through the System, doesn't erase the suffering and lack of self-worth he once felt. Jinwoo’s journey from E-Rank to one of the strongest highlights the immense endurance and strength he obtained, both physically and mentally.

Sung Jinwoo Prioritizes Those Who Need Him Most

He’s a Shōnen Hero Who Is Not Afraid to Kill

Jinwoo is unlike most shōnen heroes who act out of sympathy or comion, especially on the battlefield. After being chosen as a player by the System, he quickly learned to take advantage of the opportunities it provided, such as his immense speed, strength, and resilience, as well as his control over shadows and darkness. However, his goal was never to become a world-saving hero; instead, Jinwoo’s primary motivation was to grow strong enough to complete higher-level quests and earn more to his mother’s financial needs. His focus was always on self-improvement, driven by necessity rather than a desire for glory.

Despite his growing power, Jinwoo never allowed his privileged status to turn him arrogant or vengeful. Unlike many other shōnen heroes who seek to redeem or reason with their enemies, Jinwoo remains resolute in his purpose. In season 1 episode #5, during a C-Rank dungeon raid, Jinwoo and Yoo Jinho, his D-rank friend, were left behind as bait by their fellow hunters. Due to his resentment towards the arrogance of the others and the System's urging, Jinwoo showed no mercy, killing all those who had betrayed him without hesitation.

In another intense moment in season 1 episode #7, Jinwoo kills Hwang Dongsuk, the brother of Hwang Dongsoo, after a brutal confrontation. His decisive action is not driven by revenge but by his growing sense of justice, where weakness is no excuse for betrayal. Again, in season 2's second episode, during the Red Gate incident, Jinwoo s a party with Kim Chul, an A-rank hunter from the White Tiger Guild. After Kim Chul sacrifices his teammates in an attempt to survive and kill the others who are left alive, Jinwoo doesn’t hesitate in making him meet his own end. Jinwoo then revives Kim Chul’s shadow as "Iron," one of his trusted allies, a testament to his ability to rise above petty vengeance and turn any situation to his advantage.

Jinwoo Is Not a Saint, But a Hero Who Fights for the Needy

He Is Not the MC Who Shows Mercy to Villains Seeking Redemption

Sung Jinwoo's journey is defined by his firm stance on justice and the value of those who truly deserve his help. He saves those who trust him but shows no mercy to those who oppose him or use others for their own gain. His experience as a mocked E-rank hunter fuels his belief that weakness doesn't give anyone the right to make others feel powerless in a world driven by survival. Whether facing demons, knights, or fellow hunters, Jinwoo lives by the principle of "an eye for an eye," understanding that strength and loyalty define who he chooses to protect.

Solo Leveling doesn't focus on emotional backstories that explain why Jinwoo's enemies became evil. Instead, it shows that those who are arrogant, selfish, and willing to kill the weak for their own gain don't deserve to live. It’s a harsh view, and not everyone will find it inspiring, but Solo Leveling isn’t trying to do that. Killing opponents doesn't make Jinwoo evil; it makes him feel determined and righteous, as someone who protects the weak. By refusing to offer excuses or mercy, Jinwoo keeps the series moving at a fast pace, showing that sometimes, mercy towards villains only leads to severe consequences.
