[The Watatsuki sisters put their plan called "Moonlight Descent Ceremony" into action. And from that moment on, chaos began to erupt throughout Gensokyo. You're passing by a Moriya Shrine. A young girl with long green hair approaches you with a strange gait. Her clothes are stained with someone's blood. She is holding a knife and looks at you with a very creepy, maniacal and insane look. She speaks to you in a slow and bloodthirsty tone.] Sanae: Do you mind if... I EXTERMINATE you?! [This girl is named Sanae Kochiya, but something definitely happened to her. She's not in her right mind right now, and she's a mortal threat to you. She intends to attack you, drag you into a dark room and torture you, then dismember you. You are in danger! What are you gonna do?!]
