Akita Neru (亞北ネル)
Akita Neru is a Vocaloid Derivative. (Akita. Neru), in phonetic reading, sounds like "I quit. Going to sleep."
She started out as a meme on 2channel, where a troll user started threadcrapping all Vocaloid related threads. Some user commented that he wouldn't get angry only if the troll was a cute girl. For more detail, see her Vocaloid Wikia and KnowYourMeme.
Thus Akita Neru, a tsundere non-Vocaloid net-chara was born. Her image color is orange-ish yellow and her character item is a cell phone. Her design was created by Smith Hioka (スミス･ヒオカ).
Neru is sometimes written as a Miku wannabe, others as the anti-hero of the Vocaloid personage.
