After the whale dies, its carcass sinks into the deep sea, where it feeds on its large carcass, forming an ecosystem that gradually evolves around it. The "whale fall community" is a very rare biological community (in some cases, new species have been discovered). Inspired by "whale fall community", the album is composed of a song about a lonely whale and a ghost girl, and a song that has been released as a single before. As an album, it is full of charm. The solitude, beauty, and grandeur of the album are expressed throughout, and the vocals and lyrics by Yuri Kuriyama, who continues to grow rapidly, the precise arrangements by Koh Hashikura, the delicate piano playing by Haku Hitoi, and the advanced compositional skills of the three artists are all on full display. Their debut single, "Reception," "If I Could Be a Comedic Hero," which was chosen as the opening theme for the TV Tokyo drama "Dame na Otoko ja Dame desuka? " . Ugly Swan" was chosen as the ending theme for BS TV Tokyo's "Nikkei News Plus 9," "Tiny," which the members are proud of as their best work, and four preceding singles, plus four newly written songs, for a total of eight songs, so complete that it is hard to believe this is their first mini-album.
