It has been announced that Memai Siren's new song image _____, which is produced and arranged by TK (Ling Tosite Sigure), will be released on January 22 next year.

The song will be used as the ending theme for the upcoming TV anime series pet. The opening theme is entitled Chō no Tobu Suisō (The Water Tank the Butterfly Flies in) and sees TK from Ling Tosite Sigure taking the helm to perform the song.Both the anime edit version and full version of image _____ will be made available for digital download on January 6.   Memai Siren said: "There's a lot of things in pet we can relate to. It looks at the mountains and valleys of people's hearts, and questions if what we're looking at really is reality. We set out to create a song from the perspective of the storyーone that can support people. And with TK kindly on board to produce for us, we believe we have been able to elevate our expressive power like we never have. However, the reality in which I am writing this right now: is it just a memory? Or am I just rewriting something? Does this song even exist in the first place? I entrust the answers [to these questions] to you, the listeners."

Japanese rock band Memai Siren will release their new CD single Yūdachi on February 6, 2019. In the run up to its release, the anime edit version of the track is now available on streaming platforms.   The song serves as the second ending theme for the ongoing anime series Karakuri Circus.
