Saw in the tweet replies some interesting details in this picture.
Pair of ringed circles above Aki representing Makima. Also his ghostly younger brother behind him and a gun off to the right. Near the footprints there also seems to be 6:12 written out. Could refer to something else but I took it as a bible verse. I'm not religious at all but a Google search brought up Ephesians 6:12, reading "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Ah, I hadn't noticed Aki's younger brother. Good eye! I was also wondering about the number. It has been a while since I read Chainsaw Man, but upon a hasty rereading, the 6.12 directly references the colored page in chapter 79 containing a group photo of Denji, Aki, and Power. Not sure what the number means itself though. I completely forgot about the ringed eyes while tagging! Would it be appropriate to add ringed eyes and perhaps ghost to the tagging?
To be honest I'm not sure about adding the ringed_eyes tag, since without the context of a face I couldn't really call them eyes. More like a conspicuous arrangement of circles symbolizing a specific character. I will go ahead and add the when_you_see_it tag though. As for Aki's brother I'm not sure whether he's supposed to be a ghost or merely a faded silhouette, so I think we lack the conclusive evidence to tag ghost. Will add his character tag and change to 3boys.
