Dandadan Chapter 21

Chapter 21 continues the Serpo incursion into everyday spaces: after the immediate scuffle, Aira is revealed to be superhuman as well, attracting the Serpo’s attention and complicating the conflict. The crab-headed subordinate becomes a more active threat, engaging Aira up close while Serpo commanders strike from a distance; the battle choreography emphasizes close-quarters combat and the awkward vulnerabilities of the protagonists.

On the character level, the chapter focuses on emergent teamwork and identity: Aira’s surprising resilience and Okarun’s protective instincts deepen their bond, while Momo’s arrival to counter the Serpo’s psychokinesis underscores her role as the stabilizing force. The use of Momo’s psychokinesis to counteract enemy control highlights the series’ theme that emotional clarity and cooperation can blunt otherwise overwhelming power.

Plot-wise, Chapter 21 advances the Serpo arc by establishing that multiple humans manifest yokai-linked abilities, making Aira a new focal point for alien interest. The combat ends with fragile equilibrium—the heroes survive but are now more visible to cosmic predators—so the dandadan manga’s stakes keep rising as ordinary life becomes increasingly dangerous.
