Akita Neru is a derivative character. In October of 2007, soon after Miku was released, a TV program in Japan degraded the users of Miku, Miku's pictures became unavailable to search in main search engines, and Miku's article was deleted in Japanese Wikipedia at the same time. These news became widespread or "flamed up" in 2ch, then many writings to lay the news to rest or "to put off the fire" followed. The postings were with the phrases "飽きた、寝る。 (Got bored. Going to bed.)" or "寝る、お前らも寝ろよ。 (Gonna go to bed. Follow me, y'all!). Soon other users made a personification character for these postings as "Akita Neru", which Smith Hioka, the designer, later finalized. Neru came to represent the tsundere culture of Vocaloid.
