Olivia released her sixth mini album, "Trinka Trinka", on September 17 with all new material. It featured "Rain", which was used as the second ending theme to "K-tai Investigator 7". The track line up confused fans as a few of the track titles were changed, such as "Real Love" which she premiered during her Paris concert, which was renamed to "Your Smile" and quite possibly "I'm So Excited" was retitled as "Trinka Trinka". Following the release of this mini album, Olivia held a live show on October 24, 2008, at Shibuya Womb.
