I feel like we won't see ever again adv. Coc being drawn like wano.
I am sure that G4 used adv. Coc against kizaru, kizaru statement about how strong it was and how he could see how he managed to beat kaido is better than visual reference when Oda this chapter just did:
1. Zoro Imbuing one sword, other twos are white.
2. Zoro sword disappears from his mouth
3. Zoro sword is back on his mouth and is imbued with Haki like the other sword, so now two swords that we can see (we can't see the other one) are imbued with Haki.
And we wanna trust Oda when it comes to the visual aspect?
