Given that Jellyfish Can't Swim in the Night is (at least partly) marketing for a manufactured pop act, one which bestows the act with a fiction in which it is organic and the songs (and the artwork on the merch) are emotional expression for the characters, the way the story is partly about justifying double identities seems like it thematically works in support of the project's nature.
Posting about some of the manga I read. I read manga in Japanese.
