In October, another single, Koi Karasu, was released, but at the end of the year, Ryoga and Mio suddenly left the band, with one of them joining Gemini and another going to Pablo Honey.

The year 2010 seemed to be slightly unlucky for Awoi. Drummer Hiro left the band due to personal reasons after their live at OSAKA MUSE on April 17th. However, the band didn't stop their activities. Moreover, they released their first album, Aoi, in July which contained songs from the band's previous releases.
In August they hired two new members to fill the gap. Hiro was replaced by new drummer Ryo and second guitarist SIN. This brought a slight change to the band's sound--it wasn't minimalistic anymore. With the new lineup, Awoi released the single abelcain, which was accompanied by a music video, the second in the band's career.

Aoi~THE SECOND~ contained the same songs but was recorded with new members and was re-arranged for two guitarists. The album was also released in Europe, thanks to GanShin. Soon, another album was released--Birthday--also made available in Europe. It was, of course, followed by a nationwide tour, which ended with two final lives that took place on January 13th and 14th the next year at Shibuya Deseo.
Awoi started 2013 in high spirits, releasing the single Zetsubou no taiyou in April. The band made also its overseas debut at the anime convention Anime North 2013 in Toronto, Canada. Awoi ended the year with new mini-album Owari no MELODY, that came out on October 23rd.
