When a couple walks by, you can see someone staring at them from the shadows. A close up reveals that his eyes become distorted with fury or rage, and a crease starts to appear downards from his eye. Then it shows Eternal Grudge as if its either fighting its chains or breaking free.
Some have speculated that this is Shura from Canyon of Immortality. The hair is similar, but what they wear is different. Shura does not give Undead Ash, but he does drop a Demonic Runestone(10/5 Acc), and his rare drop is Avenger's Ashes. Perhaps this is him seeking to avenge something, which is why he bears an Eternal Grudge.
