EPISODE CONTEXT

Positioned at the two-thirds mark of a 13-episode season, 'Wonder Zone' arrives after the group's successful open campus event in Episode 8 and uses that momentum shift to pivot toward individual character development — specifically Kotori's personal journey. This episode plants seeds for the season's closing arc by deepening the emotional bonds and unresolved tensions within μ's. The introspection here directly sets the stage for the higher-stakes episodes that follow, making it a critical bridge between the group's rising success and the personal costs that come with it.
