That ramen bowl was used for every Marine lmao
Yeah, it's only a coincidence that Kizaru was the biggest character with it (it is his favorite meal in fact), we saw him in a position before, he changed that position after, we saw him thinking about Bonney and Sentomaru and now he is on the verge of tears about his mission.
In all of this, there are only two people who could have done that in the first place and...one is, unironically, Kizaru.
I mean, I saw theories about OP that involved half word said in chapter 200 and a weird move of the eyes in chapter 1020.
This one is literally obvious.
