The actual Yumeko shows up on the scene, creating a three-Yumeko situation that blows the whole scheme wide open and sends the episode into full chaos.

📍 ARC CONTEXT

Sitting at episode 138 of 694, this falls squarely in the show's early-to-mid run, where episodic adventures continue to flesh out the core cast's personalities and abilities. It follows episode 137's more conflict-driven premise involving Kemumaki's schemes forcing Hattori from home, pivoting here to a lighter, character-focused outing centered on Tsubame. The next episode shifts focus again to Hattori's own ninja techniques, maintaining the series' pattern of rotating spotlight across its ensemble.
