### Summary
This chapter dramatically shifts from the preceding emotional heartbreak to high-stakes action. A tense confrontation between Cain and the antagonist, Sid, is suddenly interrupted by the appearance of a new, unnamed character—a blue-haired man with piercings, whose antagonistic demeanor and mysterious identity lead readers to speculate he may be Satan. However, the chapter's defining moment is the heroic intervention of Marshey, who reveals a new, powerful form as a gigantic, monstrous flying demon. In a triumphant rescue, Marshey saves Kyungjoon and others, cementing the creature's status as a beloved fan-favorite. While the introduction of the new potential villain adds another layer to the conflict, reader sentiment remains firmly focused on the existing antagonist, Sid, with many expressing a strong desire to see him face justice without a redemption arc.
