EPISODE CONTEXT

As the first of fifteen episodes, 'Hitagi Crab, Part One' is the foundational entry point for the entire Monogatari franchise, establishing Araragi as the supernatural-adjacent protagonist and Senjougahara as the first of several characters whose afflictions drive the series' arc structure. This episode is the first half of a two-part opening story, with 'Hitagi Crab, Part Two' directly continuing and resolving the initial mystery while cementing the dynamic that carries through the full season. Each subsequent arc introduces a new character and supernatural case, but the tone and relationship groundwork laid here inform everything that follows.
