I've seen a few comments about this guy and Satsuki K2 with a sword, what's the connection?
He really likes Satsuki. Almost all of his work on Danbooru are dedicated to Satsuki, well, the "Destroyer's Destiny" series, I mean. And as theSandwich said, he stated his one and only wish was that Satsuki Kai-ni would have the sword her captain had.
