Solo Leveling: Ragnarok, the sequel to Solo Leveling, focuses on Sung Suho, son of the original protagonist, Sung Jinwoo. While fans enjoy Suho's story, they are also curious about the fate of Jinwoo and Cha Hae-In. The webtoon reveals Jinwoo is fighting a powerful enemy in space, but Cha Hae-In's whereabouts and status remain a mystery, leaving fans wondering if she's alive and where she might be.
Sung Jinwoo, though powerful, couldn't face the multiple Itarim Gods threatening Earth. He left to fight them in space, leaving his son behind. The question remains: what happened to Cha Hae-In? The Solo Leveling novel reveals she was drawn into a separate dimensional rift created by the Itarim's Apostles while flying with Kaisel after the original series' ending. This rift, unlike Jinwoo's, closed, trapping Cha Hae-In and Kaisel in a dangerous dimension for years.
Before leaving Earth, Jinwoo suppressed his son Suho's powers for a normal life. However, with the reappearance of Gates, Suho's powers awaken. Beru informs Suho of Jinwoo's space battle and reveals Cha Hae-In disappeared the same day. Suspecting the Itarim's involvement, Beru tasks Suho with finding his mother. Suho eventually does reunite with Cha Hae-In in the novel after she and Kaisel survive for five years in the other dimension, returning through a reopened Gate. Webtoon readers will have to wait for this reunion.
