New songs are released from Lantis, a music label operated by Namco Bandai Music Live.
The new song has been chosen as the opening theme for the TV anime “Welcome to the classroom of supreme ability 4th Season 2nd grade 1st semester”!
The song “MONSTER” is an aggressive song that is suitable for the new chapter of the show, with the intense and profound sound that is typical of Eir Aoi and the addition of digi-rock elements. The lyrics were written by Eir Aoi herself as a tribute to her work.
The CD containing “MONSTER” will be released on Wednesday, April 22, 2026. The CD will be released in three formats (Type-A disc]
[Type-B disc] and [Type-C disc], and will include “MONSTER” and three new songs.
In addition, a “limited edition disc with goods” will be released exclusively for the “Eir Aoi Official Fan Club ‘EIR GUILD'”. We hope you will take this opportunity to join the fan club.
■Eir Aoi Comment
I am very happy to be able to sing the opening theme for “Yojitsu”, a work loved by everyone.
I am very grateful for the opportunity to be involved in the production.
This time, the music is intense and the lyrics are based on the theme of the monster Ayakoji-kun as seen from the surroundings.
I hope you enjoy this song, which has a digital rock feel and gives you a new Eir Aoi, along with the anime.
