Why? You should look at how RenderingStar and E-Mann play Kokoro. They praise her as a character & do very, very well with her. I've been on the recieving end.
Lol never mind, I was probably just tired, but I lost to another kokoro and I was like !! Then I won super easily with Helena, maybe I'm just bad at mirrors?
I was bad at mirrors as well. I hated them. After more and more practice and studying my character, I came to love mirrors than any other matchup. I can shut down most Ayanes with zero issue.
