The "Expressive Poker Face." Final boss of Touhou 13.5: Hopeless Masquerade, and also a playable character in that game.
She is a menreiki, a kind of youkai who was born from the legendary masks of Hata no Kawakatsu. She has the ability to manipulate emotions, but cannot express emotion with her own face; rather, she relies on her collection of sixty-six masks to show her feelings, each representing a different emotion.
