We know a few members of the Grand fleet are on official duties in reverie that is taking place at the same time as the wano arc. But what about the rest of them members that are full time pirates! Is wano arc too small for them to enter?
For example: Since Bigmom has come to action and joined forces with Kaido. Doesn't hajiruddin's entry makes sense?
I mean they looked for support everywhere (even Marco) but not SHGF why?
