Akita Neru is a fan-made parody character derived from Hatsune Miku in the Vocaloid fandom. Her name means 'I'm tired' or 'fed up and sleepy.' She has a strong, energetic image with blonde hair and often opposes Miku but always loses. Portrayed as one of the world's top five strongmen, she excels in various competencies, including dirtier dealings like assassinations. Despite her tough exterior, she is surprisingly innocent, blushing around Len. She works as a writer for an advertisement agency and is a tsundere beloved by fans.
