Kuroneko Meeting

The Black Cat Secret Meeting (黒猫秘密集会, Kuroneko Himitsu Shuukai) is a relaxation day, which used to be held once a year, but moved on to once every century, because at first, it was a social gathering for only Black Cats, but then Shinigamis were welcome as well, and as the Shinigamis were consecutively winning in every game, it turned into a serious battle, as the Black Cats resented their losses and started preparing harassed goods as the next secret winning prize for the Shinigami team for every next meeting.
