I saw an insanely cute female Killua cosplayer a few years ago and I haven't been the same since. She looked like Rebecca Chambers and had a fantastic costume + wig, I felt my heart melt.
I really want to recreate that sort of "ninja assassin bratty girl" thing in my writings but it may be hard to get away with. Thinking of something like the far left Killua, but with black hair and baggy khaki pants. I'm so alone.
