Quruli will release their new single "Koto Koto Kotoden / Akai Densha (ver. Tsuioku no Akai Densha)" on December 25.
"Koto Koto Kotoden" was written with the motif of the Takamatsu-Kotohira Electric Railroad, also known as "Kotoden," and it features Homecomings's Tatamino Ayaka (Vo) as the guest vocalist. The band performed this song in 2011 during Kotoden's 100th year anniversary event. Since 2015, it has been used as the departure melody at Kawaramachi Station. However, this will be the first time that this song will be officially released.
Meanwhile, "Akai Densha (ver. Tsuioku no Akai Densha)" is another version of "Akai Densha" which was released as a single back in 2005 after the band received an offer from Keikyu Corporation.
