對國中生活充滿期待的「小心」安西心，才過了一個月就感到徹底絕望，因為她受到班上同學真田美織的欺負，但更讓她心寒的是，原本無話不說的好友小萌竟然也加入了排擠她的行列。
恐懼與不安緊緊糾纏著小心，只要一想到上學，她就渾身不對勁。小心開始足不出戶，將「心」封閉在自己的房間裡。
直到那一天，房間的大鏡子突然放射出七彩光芒，小心好奇地伸手一摸，整個人就被吸了進去！鏡子的彼端聳立著一座孤獨的城堡，小心不敢相信自己的眼睛，以為一切是在作夢，此時一位戴著狼面具的女孩乍然現身：「安西心同學！恭喜你被選為這座城堡的特別嘉賓！」
「這裡是哪裡？」「為什麼她會知道我的名字？」小心還來不及回神，城堡的鐵門便已緩緩地打開，裡面還有其他六名跟小心一樣的國中生。狼少女不疾不徐地向大家宣布：這裡藏著一把鑰匙，找出來的那個人，就可以實現自己的願望……
