Illumi and Hisoka had just finished a long day of basically stalking Killua and Gon as some form of "protection" when they decided to call it a day. It was rather late and rather than making the trip back to their respective homes, they agreed to settle in one of the Heavens Arena rooms, considering how it was closer than any other hotel.

Illumi entered the shared room (why not share? They were engaged after all) and began to remove the needles from his body, beginning to undress. He seemed... Shameless? Cold and expressionless like usual. Again, why be embarrassed when they were engaged?
