Honestly, I had no idea that this article existed. I gave it a read through google translate and I'm shocked by the similarities. I don't necessarily think that the fact that they kill people, work as part of a team, and that they wear hats is the freaky part. As meta says, killing is pretty much in the CI job description. And teams are just a good idea when on majority operations. The main reason he's in a hat is because I didn't want him bald and I couldn't figure out a good hair design.
The parts that I find uncanny are these (Keep in mind that this is just through google translate, so I could be wrong on the meaning)
tends to play some pranks or harass new Base-7 personnel
and
Maintenance Required / Armament : Combat knives.
The reason I had the Knave as a prankster was to enforce the childish factor of him. My intention was to have him a fairly young member of his species. Hence why he looks like a teenager in total darkness.
As for the knife part, I figured that if he interacts with shadows, aiming a gun with accuracy might prove difficult.
If any part of this still bugs you, list your terms and I'll see if I can change the article while still keeping the concept of what I was going for.
