Singer-songwriter unit RYTHEM, who disbanded in 2011, have restarted their activities on May 21.

On their official YouTube channel, RYTHEM members YUI and YUKA will be singing various songs with no cuts or microphones. As part one of this project, they have uploaded a video of themselves singing "Harmonia," which was previously used as the ending theme for anime 'NARUTO.' 

In addition, RYTHEM have established an online community called 'Rythem no Mori' where they will be connecting with their fans and preparing special content. For the time being, they will be basing their activities there.
