Plot and background

One of my favourites...

Adan no Shima Tanjyosai or Luminescent creatures is one of my favourite songs from the album! Being the climax of the story, with the girl turning into a bioluminescent creature by the end, the song perfectly captures the incredible loneliness that bioluminescent creatures must've felt, quoting Ichiko, that they had evolved to light themselves up in the dark to find a mate. Human beings are not separate from nature. And the only way we can reconnect with it is by returning to its cycles. The protagonist faces displacement in the beginning of the story, but finds herself immersed by the sea, revealing that we can only find harmony through truly being with our environment.
