WhileSolo Levelingseason 3 remains unconfirmed, fans have yet to recover from the massive success of the second season, especially after Sung Jin-Woo wonCrunchyroll’s Best Main Character award for 2025. Fans are more eager to witness Jin-Woo’s upcoming adventures, including the development of his relationship not just with Cha Hae-In, but also with his sister, Jin-Ah.
In the first two seasons ofSolo Leveling, Sung Jin-Woo’s sister, Sung Jin-Ah, consistently played a small but meaningful role. Unlike other female characters, she has no magic abilities and is unable to exist in the same world as the hunters. Even so, she remains a relevant character, someone who supports Jin-Woo emotionally and psychologically. However, her relationship with her brother is about to change in Season 3 and here’s why.
What Kind of Sister Is Jin-Ah to Jin-Woo?
Jin-Ah Is Not a Troublemaker
According to Sung Jin-Woo, his sister Jin-Ah is just like any other ordinary teenager. She goes to school, studies, unwinds, eats dinner, and goes to bed right after. As revealed inSolo Levelingchapter 50, every time Jin-Ah comes home from school, she turns into a sleepyhead who likes to eat fried chicken. And back in middle school, they’d hit it up at the arcade and play games until the sun set. This ishow Jin-Woo sees his sister, contrary to Han Song-Yi, who thinks her friend has nothing to do but study.
“Are people going to call you Boss now?"—Sung Jin-Ah to Jin-Woo
From the beginning, Sung Jin-Ah has always been aresponsible sister to Jin-Woo. She’s not problematic, unlike other teenagers who often cause trouble. She also understands the poor living situation of her family, going so far as to consider dropping out of school to help Jin-Woo earn money. Despite the cruelty of the world she lives in, Jin-Ah remains positive, often finding joy in doing random things with Jin-Woo. Whether it’s eating chicken or exercising, she appreciates the small but important things in life.
How Will Jin-Ah and Jin-Woo’s Relationship Change in Season 3?
Their Bond Will Grow Deeper Than Ever
As shown in theSolo Levelingmanhwa, season 3 is expected tochange the relationship of Sung Jin-Wooand Sung Jin-Ah due to an unexpected encounter that will draw them closer than before. While the first two seasons explored the goofy and fun side of the siblings, Solo Leveling season 3 is expected to show how deeply they care for each other. As the stakes go higher, there’s no more time for the Sung siblings to mess around with each other.
In the remainder ofthe Ahjin Guild arc, Sung Jin-Ah’s life will be in danger, traumatizing her in the process. Her horrifying experience at the hands of the orc warlord, Guroktaru, will change her personality in an instant. Although she will survive the encounter, thanks to Jin-Woo, her fun and outgoing self will cease to emerge. Instead, she will worry about the safety of her brother, her mind filled with the most awful possibilities.
“The weather’s bad. I wonder if Jin-Ah brought her umbrella”—Sung Jin-Woo
As a result, Jin-Woo will learn to be more sensitive around Jin-Ah. He will think twice about his choices, as they could inflict more trauma on his sister. Still, he has no choice but to move forward and face the loomingthreat of the Monarchs, despite the reservations of his family. In other words, the fun and games between Jin-Woo and Jin-Ah will gradually disappear, but their bond will grow deeper than ever.
Will Jin-Ah Awaken and Become a Hunter?
Jin-Woo Says No
As much as fans would love to see Jin-Ah become a hunter inSolo Leveling, she will not awaken magic abilities. And even if she did awaken her abilities, Jin-Woo has strongly rejected the idea of his sister going to the battlefield and risking her life. It’s enough for Jin-Woo to see his sister enter medical school, complete her training, and become a doctor in the future.
“It’s alright now. Sorry I’m late”—Sung Jin-Woo to Jin-Ah
Whether Jin-Ah awakens her magic abilities or not, she remains a far greater support to Jin-Woo than all the healers and mages combined. Without her, Jin-Woo’s life would have been lonelier and more difficult, considering the heavy burden he had to carry since the first season. Thankfully,Solo Leveling’s creator, Chugong, did not remove Jin-Ah from Jin-Woo’s life until the end.
