Seoul Station Field Arc

This fourth arc of Solo Leveling: Ragnarok covers Chapters 21 through 29 in the novel and Chapters 16 through 24 in the webtoon. It sits between the Gwanak Mount Field Arc and the Beast Sanctuary Arc, with the action moving through the Shadow Dungeon and the Seoul Station Field. The cast on record includes Lee Minsung, Lim Do-Gyu, Esil Radiru, the shadow Brocky, and Han Jaehyuk, with beasts such as the Spiked Lizard and Mist Burn present.

The arc's notable clash pits Suho and Esil against inferior demons that have been enhanced with Stardust, a fight that ends in the demons' deaths. Progression is a major thread: Suho reaches level 20, which opens access to the System's shop. He also pulls the Vulcan's Horn from a Cursed Random Box and later obtains the Ashen Ring. A significant reveal exposes that Stardust is a creation of demons, and the method behind its production is laid out as well.

Esil makes her entrance here too, though in a diminished state, her power reduced to that of a C-Rank Hunter. The adaptations differ on one item: in the novel the Vulcan's Horn takes the form of a sword, while the manhwa renders it as a gauntlet.

Suho leaves the arc with the System's shop unlocked, two new items in hand, and fresh knowledge of where Stardust comes from. Esil's reduced presence sets up her arc going forward. The story then advances into the Beast Sanctuary Arc.
