Yup
Some Japaneses realized the first time he put the suit in 1074😊
It seems oda was trying another colors
But at the end it was a clear reference to him
At this point i'm even questioning if Zoro and mugiwaras will fight nasujuro and the other gorosei even if he has the oniteru I zoro doesn't need that sword he will be the WSS with the III one

he didn't take the II one so why he woul take the I one

Reminder that 40 and 60 yo Zoro will also be ranyaku master
