This is a scene from the flash video for the song Tsurupettan. It's a song about a Suika Ibuki's flast chest. She's a Touhou character from the game Immaterial and Missing Power. This particular scene references the song "Let's Go! Onmyouji!" with Suika saying the lines "Akuryou taisan/Evil spirit begone!" and "Douman Seiman" (Buddhist chants), which is the chorus in the Onmyouji song.
