and the bandmates started living together, calling their home . Noguchi from Guild also started living with the band. Noguchi helped the band in the studio and at lives, and became an official member on December 13, 2011 as a keyboardist and synthesiser user, before the release of their second album Portal. Noguchi, originally a bass player, found it difficult to get better at using synthesisers. In Galileo Galilei, Yuuki Ozaki was the main lyricist songwriter, and would give ideas to Iwai and other band members to work on further. Iwai did not feel confident in his ideas and lyrics, however wrote the music for their 2011 single "Asu e", and worked on many of the songs on Portal (2012), including most of the work on the instrumental song "Blue River Side Alone". Iwai started to feel like he wanted to influence the Japanese music scene more by himself, and in July 2012, during the demo sessions for Baby, It's Cold Outside, told Ozaki that he wanted to be the front man of his own band.

However, in late 2012, Fumito Iwai heard his brother composing the song "River", and enjoyed it so much he asked to arrange the song. On New Years Day, Fumito Iwai unveiled his completed arrangement for the song, which all the housemates loved. Takahashi suggested they merge their two bands to create a five-member band, which lead to the formation of Folks. The name Folks was chosen to represent the band being a community
