I don't know what prompted this ask bc I don't recall speaking about reading Dandadan in public but uhhh it's the St Germain arc! He's progressively isolating and neutralizing the main cast through a variety of different means. I feel like the way everyone's fighting a range of independent battles (And in some cases, almost refreshingly, losing!) rather than all being focused in one place/with one goal is resulting in some confusion but the overall narrative premise is simple: the villain is trying to steal everyone's powers and has hired scores of sub-villains to do so. A principal component of the arc is "loss" imo and dealing with being "less than" your usual self (Okarun is stripped of his powers first and has no "right" to return to them unlike the others, Momo has lost her memories etc.).
