Posting about some of the manga I read. I read manga in Japanese.
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.
If a book is a translation, I think it's a good sign if the translator credit is easily noticeable. Title page at least, but preferably the cover. Especially for novels, but comics too.
Kashikaze (creator of I Can't Say No to the Lonely Girl) will be doing Howling song for husky girl (Kimi ga Hoeru Tame no Uta wo,), which seems to be about one girl creating songs for another girl who likes to sing but has a husky voice and worries it doesn't suit how she looks.
Usui Shio (creator of Doughnuts Under a Crescent Moon and I Married My Female Friend) will be doing Bokura no Ai wa Kimochi Warui, which is apparently about the protagonist having a kink that she thought she couldn't tell anyone else about. Presumably, from the image, it's doll fetishism (pygmalionism?) and the other girl finds out.
Usui Shio also currently has non-yuri series #Moto Idol no Hello! Work running in Manga Time Original and a yuri series called Koi ni Koi suru Koibito Kankei running on Storia Dash.
