one interpretation- Maybe the back tattoo is a reminder of Doumeki's commitment to reach him, especially intense cause his devotion continues to risk his life. Could be all the emotions Yashiro was holding in now overwhelming him seeing D alive.
-not sure of any reference - perhaps he got the tattoo coloured in? been a while since I read from start.
I wonder if I’m missing something when some panels show closeups
I’ve seen people post about some parallels between chapters, with scenes side by side, but some stuff is so subtle
Like why did yashiro look shocked on page 20? He has already seen the tattoo and the shock from doumeki’s outburst was shown in the previous pages
