Koha lends her voice as the lead character of the anime Kirarin Revolution, which started in April of 2006. Although the show doesn't really seem to be all that popular, it would seem that Koharu enjoys it. On top of being the main lead, she also sings the opening theme songs. So far, she's released 2 of these themes, and both fit the character perfectly.

More information coming soon. ^^
