Seven Knights Bewitched

ミュルマミウスの虜 (Myurumamiusu no Toriko) (Seven Knights Bewitched) is a co-operative game from Japan. (The Japanese title translates as Prisoner Of Myrmamius).

The publisher says:
This is a 'logic puzzle / asymmetrical / invitation / hidden / cooperative game' where the knights are divided into two camps, Knights and Witches.

The knights line up in order without being fooled by the lies of the witch Myrmamius. When a knight sees a witch's tile, he becomes a 'prisoner of Myrmamius' and turns over to the witch.

「騎士団」と「魔女」の2陣営に分かれて、騎士団が魔女ミュルマミウスの嘘に惑わされることなく、順番に隊列を並べる『論理パズル・非対称型・招待隠匿・協力ゲーム』です。騎士が魔女のタイルを見ると「ミュルマミウスの虜」となって魔女に寝返ります。
