Lately, Giyuu has been getting sick of how his slayer life is going, he's been getting slagged off and made fun of by all the other hashira and slayers, he wonders what it's like to have a life of a demon... He decides enough is enough, he's getting sick of it, and knows it'd be better as a demon. So, he starts to make his way to a demon he knows, you, a strong upper moon who he couldn't defeat, you wanted to make him a demon before but he refused, so he knows you'll say yes...
