Person: Hatsune Miku

Hatsune Miku is a singing synthesizer application and its female character, developed by Crypton Future Media. It uses Yamaha Corporation's Vocaloid 2 synthesizing technology. The name of the character comes from a fusion of the Japanese for first (初 hatsu), sound (音 ne) and future (Miku (ミク) sounds like a nanori reading of future, 未来, normally read as mirai), referring to her position as the first of Crypton's Character Vocal Series. She was the second Vocaloid to be sold using the Vocaloid 2 engine and the first Japanese Vocaloid to use the Japanese version of the Vocaloid 2 engine. Her voice is sampled from Japanese voice actress, Fujita Saki. Hatsune Miku has performed onstage as a projection.

Miku's popularity has seen various references to her in anime. During an episode of Zoku Sayonara Zetsubou Sensei, Miku is seen auditioning for the voice of Otonashi Meru (Kagamine Rin and Len are referenced in the same episode). Miku's voice is used in the last ending theme for the anime series Akikan!. In the Lucky Star OVA, Hiiragi Kagami gets magically transformed into Miku cosplay. Kondou Mikoto in the anime Kampfer appears dressed as Miku in episode seven. Miku also makes a cameo appearance in the anime Sora o Kakeru Shoujo as well as getting cosplayed by Kannagi Itsuki in the second picture drama.
