B≡FULLEST is a new project formed by three former members of Niji no Conquistador: Riko Shimizu, Akari Nakamura, and Moe Tsurumi.

The concept centers on three girls portrayed as “goddesses who have fallen from the heavens to earth,” embarking on a new journey in a world where ruins and flowers intertwine. Within this dreamlike realm, they encounter the “moment when something precious comes to an end” (referred to as Nanika), transforming that emotion into music as they weave a story of collecting “shining feathers.”

The worldbuilding, script, and direction are handled by Takuto Aoki (ILCA Inc.), known for his work on the NieR series and SINoALICE, depicting the fragile yet determined lives of the girls through both musical and visual expression.
