Mio first appears halfway into the anime series. She is a character exclusive to the anime version of D.N. Angel a student who suddenly transferred to Daisukes school as shown in episode 14. All that is known at that time is that she left for America and stayed there for 2 years before coming back to Japan. First impressions of Mio is that she is a rather simple minded quotvalley girlquot or an American gaijin in the Japanese version even going as far as to say quotSorry I cant speak Japanesequot when confronted with certain demands or in the English dub telling Riku in Spanish that she cant speak English.
