Invisible gloves?
Has this shadow demon gone blind?
Why does he see a hand that isn't wearing anything?
Just what kind of monster is this human shopkeeper?
Nested within the shadows resided a dragon-like shadow demon, and this man, barehanded, could yank the shadow demon out of the shadows. Even the Holy Knights and ascetics of the temple, without some means to restrain them, couldn't easily extricate a shadow demon from the shadows.
Shadow demons merge with the shadows.
When they assimilate into the shadows, they become a part of the shadows.
For example, can a human standing under the sun lift their own shadow off the ground?
No.
When shadow demons blend into the shadows, they have no physical body. Not to mention dragging them out, under normal circumstances, one cannot even see them.
Yet this human could not only see him but also pull him out of the shadows and capture his intangible form.
That's absurd.
