As for that club scene...It's something that I never thought about until now, but this series is written by a dude, isn't it?
Tomohiro [知宏] is definitely a male name, but then again, James Hotate is female and Lynn Okamoto is male; Manga-Updates says “female” but doesn't provide a source and that often comes with random things about that things that aren't confirmed, but the Japanese Wikipedia page for this artist also says “female” and does come with a source, which says: “
『鈍色の箱の中で』第6巻あとがきにて出産したと記述あり。” meaning “The afterword of the sixth volume of
In the Blunt Box had information that the artist gave birth.”. I have never seen the afterword, or even knew that this work existed and what it is. All I know is that it's the same artist who also made
Boy Skirt, which surprised me because they're very different but the art-styles are very similar.
Why would the club scene imply the artist is male though?
