Yesss.... Zoro in his LAST ATTACK with Asura on Kaido... he stated that he will put out ALL HIS STRENGTH in that last attack... so basically it should all his haki that remained was put into that attack... meaning he should have run out of Haki...
Not only Zoro or Katakuri... you cannot convince me that no other character doesn't run out of Haki... no one uses haki as much as Luffy does...
So let me guess... when Shanks ALL STRENGTH and HYPE comes from his Haki... meaning his entire fight will be focused on advanced king's haki... and he's activating it for a long time.... ARE YOU GONNA TELL ME that Shanks will have a 10 min haki break like Luffy? LMAO, such bullshit
