Just caught up. The last dozen or so chapters have been a blur. Are we in the final arc?
no , this arc is a blur because it's the turning point of the series in which a major mystery is revealed, and D decides what he truly wants to do/who he wants to team up with
there will definitely be a next arc because
1. 4 executives (1 not showing up yet), giga invader, and both red & yellow keeper , all getting beaten this arc is too much
2. stealing the 5 divine tools has always been D/suzukiri's goal-
the format of the arcs is:
red (prologue, D stealing red's weapon),
blue (Blue battalion managing bailong and D getting blue's weapon afterwards),
green (green battalion vs magatia, and D attempting to kill green afterwards) ,
yellow (yellow's research revelations arc),
so
pink is next arc,
and probably all 5 finishing off red and other leftover antagonists for the final stretch/arc
