Kurai sounds a lot like Kurt, they even have the shadow part in their nickname almost the same.Not that it bugs me, they are just so much a like

My first thought was. "Why did he repost his CS?"
There are some diffrences in the background but the persona seems almost exactly the same.

You might want to adjust it somewhat for diversity.
Then again, 'the shadow' is a pretty archetypical name for an assassin. Could it be that there's multiple unnamed assassins out there that go by the name "the shadow"?
By their nature we can never know how many there are. plus it adds to the mystery. One night a guy is strangled in his penthouse in Paris, the same night someone is sniped in Tokyo. Same calling card, same name. "The Shadow".. how does he do it?
