The mischievous, cheerful best friends of Haruna, Risa and Mio
spend as much times as they can with her and Lala. Whenever Lala inquires about Earth culture and habits, the two divulge as much information as they can for her (although it is often misleading and perverted). Risa and Mio are known for their playful habit of groping other girls. Recently, it is shown that Mio enjoys cosplay and works at a maid cafe As well as it has been shown that Risa might have feelings (or at least lusts) for Rito, but it hasn't been detailed if she was serious or joking.
