[KMS]Inkwell Diary # 72 - Night Walker skill preview

The Mechanic is Aiden and Checky. Aiden has a grey hair color and red eyes, just like this artwork depicts:



That person you think it was doesn't have the robot or the robot ally.

Yes, because he's leaving and never seen again. Checky doesn't have a human design either...

However, many fan artist, myself included, take O-Nyan's design of that guy from above to be Checky's human design and treat Aiden and Checky as two different individuals. There are even KMS RP bots on twitter that use that specific character as representation. So it varies on your own personal headcanon.

Edit: I also should mention that the educational comic Hanja Thief which is Licensed by Nexon treats the two separately as well, so I personally do not think Nexon intends for Aiden to be Checky. They're two entirely different people from my perspective.
