The Guardians Arc

The Guardians is the sixth story arc/saga in Fumetsu no Anata e. It jumps ahead four decades after the first five story arcs, leaving the ultimate fate of many characters unknown.

In the ongoing anime, first few episodes of the upcoming second season of 2022 are an adaptation of this arc, set four decades into the distant future.
