He’s not nervous around Saturn, he’s nervous about Saturn protection because it is his fucking job and he’ll look like shit if anything happens to one of the 5 most important world leaders.
There’s no «portrayal », just headcanons.
Also if the Gorosei were truly strong top tiers, then Saturn wouldn’t need to rely on Kizaru’s protection in the first place right?
yet they had to call a whole fleet + an admiral just to ensure his safety
you could argue they’re just doing this to keep the public image in check (haha gorosei old and frail need guards) but they could have just kept his involvement a secret to begin with if they care about the public opinion
For now, I’m under the impression that all 5 of them have strong/OP abilities but still not enough to warrant them being top tier fighters in the verse
Admirals will remain the strongest military force the World Government has.
