Note:
Page 5: The "smoke" part isn't mistranslation. It's "煙" in RAW. It's a bit confusing since that panel shows the elf's pendant/gear. So, turns out it's a (Spoiler) Curse from the gear, even though I can't find any smoke emitted from it.
Page 16: In RAW version, the bottom panel has 2 speech bubbles. These 2 looks like they're coming from the elf, but they don't. The dialogues should be spoken by the old dud. So I remove the pointer(?) from the bubbles.

What's the point of a "dark" elf if she's barely darker than a dude? or even the background?

Don't get me wrong, this is a good work, I just don't see the "dark" elf.
