Kagamine Len is a character in the Hatsune Miku: Project DIVA series. Facial wise, Kagamine Len is notable for his blue eyes and short blonde hair with a ponytail at the back. Like Hatsune Miku, Len's attire is mainly based on a school uniform where he wears a white shirt with an yellow tie and black shorts with an yellow stripe on each leg. The shirt also displays a small yellow bass clef (F-clef). His legwarmers were designed to mimic speakers, and his boots use the YAMAHA EOS as a design base. His attire is based on his box art appearance on the Kagamine Rin & Len VOCALOID2 software packaging. Beginning with Hatsune Miku: Project DIVA 2nd, Len's attire is updated to appear more like his box art on the Kagamine Rin & Len Act 2 software.
