Tanaka Reina to Star in New Anime (Just Another H!P Blog)

Recommended reading. Reina and Macha Macha are the stars of the upcoming Onegai My Melody series, further plunging Hello! Project down seiyuu career tracks as almost half of Morning Musume are now doing voice work for cartoons.

This may mean that Reina will get to sing the theme - perhaps a duet with Macha Macha? - and better position H!P for appearances on the U.S. anime con circuit. It’d be ironic if Morning Musume become famous in the States, not as “that singing group”, but as “that seiyuu collective” by fans who discover Koha and company through their shows.
