Seems like someone asked to see if Ace had any markings under his clothes as well.

Since he can't get an actual tattoo, Ace uses one-day fur dyes to paint different, often random patterns on his fur. He first got his idea from his uncle's tattoo shop, where he often spends time, after his uncle suggested using normal dyes instead of ink.

The patterns on him change daily, though sometimes he feels like not having any. He usually keeps the most complex designs painted around his covered eye, though no one knows why. Other than those, the markings are relatively simple.
