Ok so I've wanted to write a fanfiction for this ship for like, ever, just cuz I love it so frickin much - so here we are! It seems like Illumi has failed his missions one too many times, so his father decided to test him. He would have to capture Alluka and bring her back to the family mansion, without any form of support from his family. That meant he couldn't use any of their money, couldn't live with them and most of all, couldn't call on any of them for help. Illumi knows only one person he can ask for help. Hisoka.
