Miracles aren't free. When you wish for hope, it creates an equivalent despair. That's how the balance of this world is preserved.
I made this cosplay a year ago. Not necessarily because I liked the character, but I was asked to a group - which, in the end, never really happened, but I still got the costume done. I must say that making it was quite a process; back then my skill level was kinda low and I got some help (especially with the spear), and I did a lot of research which caused me to like Kyoko more and more. So in the end, I'd say job well done, huh?
