It was during this time, in June 2005, that Otsuka made her acting debut with the drama Tokyo Friends. Unlike most dramas, the series was directly released on DVD and never aired on TV. The drama used three songs as its theme song, Boo Bee Benz's "To Me" and "Kimi to Iu Hana," as well the coupling song to her sixth single, "Friends: Sabakan Ver." All three tracks would eventually be included in the soundtrack for the drama's movie sequel.
