If you weren’t in the know (and by the know we mean Japan), Japanese convenience store chain Family Mart and Hatsune Miku are running a promotional campaign from August 14 to September 10 to celebrate the Vocaloid’s 5th birthday.
To spread word of the campaign, Family Mart created a 15-second television commercial featuring Miku singing the store’s signature jingle and posted it to YouTube on August 17, though a ripped version had been posted to Japanese video sharing site Nico Nico Douga a few days earlier.
One group of enterprising viewers saw the video and immediately got the idea for a parody, which he posted to Nico Nico and YouTube on August 19. The parody, titled “Miku LOVES Seven Campaign [Fiction]”. features a super deformed Hatsune Miku singing the Japanese 7-Eleven jingle and is absolutely terrifying.
