Markings - City Hall

I wiped the katana with another spare cloth to remove the grime that is starting to accumulate and I just made a small glance towards the freezer one last time. Aside from the blood that is starting to darken from the time that has passed, it also has dark muck in the bottom of the freezer that looks like change oil with several clumps accumulating or getting congealed.

I was about to throw the cloth away but then I saw a marking on the side of the freezer. My eyebrow raised since it was so similar.

I wiped the other side of the cloth towards the marking to clear a few smears of dirt and blood present. The markings got slowly highlighted as the grime gets removed. The markings seem to be carved by knives and the grime sticking inside where the marking is made remains as the grime on the still smooth surface got slowly removed.
