Sung Jinah

Sung Jinah (also romanized as Sung Jin-ah or Jin-Ah) is the younger sister of the protagonist Sung Jinwoo in the Solo Leveling anime.

She's a high school student who leads a relatively normal life compared to the high-stakes hunter world her brother inhabits. In the anime's depiction, she has purple-tinted hair (often shown tied in a ponytail with bangs) and is portrayed as shorter than Jinwoo.

Personality-wise, Jinah comes across as cheery, playful, and diligent—she's a hard-working student who often excels in her exams. She has a very close, caring bond with her brother, who has essentially helped raise her and supported the family financially after their father's disappearance and their mother's coma due to Eternal Slumber. This makes her one of Jinwoo's biggest motivations to keep pushing forward and protect normal life.

Her scenes often highlight sibling dynamics, including lighthearted moments where she teases or gets annoyed with him (like playfully kicking him, only to hurt herself because of his durability later on). Overall, she represents the grounded, everyday family side that contrasts with the series' action and fantasy elements.
