For anyone wondering why his dick is bumpy: it's a body modifications called pearling or genital beading , it's beads made of silicon or titanium that are inserted under the skin. And apparently it's common for Yakuza to get these beads to signify each year they have been in prison??? Don't know if the author added that detail bc of this reason or they just thought it was freaky lmao
