When discussing the most controversial moments in anime, few arcs start debate as fiercly as Bleach’s Fullbringer Arc. Officially known as the “Lost Agent Arc,” this storyline often divides fans into camps of either passionate defenders or vocal haters. At first glance, it is easy to see why this arc receives criticism. Following the epic high stakes of the Arrancar and Aizen Saga, the Fullbringer Arc’s toned-down story and seemingly slower pacing felt like a huge difference. But, when you take the time to revisit this arc it is really a very interesting exploration of identity, power, and personal growth.
