In August 2020, LOT SPiRiTS was formed by Luna Sakamoto (guitar, vocal), Kurage (bass, chorus), and Moe (drums, chorus). As their first anime theme song work, “Haru ni Kiete” digitally released on April 7.
The band has posted their comments on the song on the anime’s official website as below:
Congratulations on the anime adaptation of “The Unaware Atelier Meister!” We are very happy that LOT SPiRiTS is in charge of the ending theme of this wonderful work. We think the ending theme song “Haru ni Kiete” brings to mind the main character Kurt’s clumsy but devoted approach to everything he does, and the scenes of this work where the friends he makes who are attracted to him and whom he can trust, and walking together. We hope you will enjoy he ending scenes that shows the story of Yuli and Liese’s love for Kurt and their conflicts, along with the music.
