Burenai Ai de is a Miku music video, released on Miku's anniversary. Rohto Pharmaceutical later adopted the song for an augmented reality campaign promoting its Digi Eye eye drops. Like many of Mitchie's titles, the name works two ways, since "ai" can be read as love or as eye. In August 2014 an app appeared that played part of the track and let a 3D Miku dance on any surface.
