For the other character from Rocket Girls, see Miura Akane (rocket girls)
Akane is a fanmade K-ON! character by the VIPPERs of 2channel. Her hairstyle is ponytail with pink hair, and she plays a euphonium. She is a homeless person living in a park. Her nickname is "デビちゃん"(debi-chan). She is the first K-ON! character with large breasts.
Like Kasane Teto and other VIPPALOIDs, she was made at "架空のけいおん新キャラ作ってけいおん厨釣ろうぜww" (Let's make a fictional new character of K-ON!, and play a trick on K-ON! addicts. LOLLOL) thread. Because a careless member beforehand leaked a secret, The VIPPERs failed to fool people in Japan. However, their hoax succeeded somehow in the overseas countries.
The VIPPERs used "安価 (anka)" to make her profile. It is the biggest reason of strange settings of 2ch characters.
