Over here is a translated interview of Tsutomu Nihei, the author of Knights of Sidonia. I find it interesting that he’s aware he needs to do more to make his work appeal to female readers. I dunno, dude, maybe make it less male gaze-y? Just change up the presentation and quit with the harem antics and fanservice.
It’s not like Sidonia’s subject matter or setting are alien to shoujo or to female readers. I mean, Please Save My Earth had psychic death battles and They Were Eleven began with a giant info-dump about fusion reactors and space empires – things that should be pleasantly familiar to old school grognards stuck in the sci-fi ghetto. (The latter also had transgender aliens reenacting And Then There Were None in space, but I digress.)
Though I do wish the interviewer had asked Nihei more about his science fiction influences. Which novels did mini-Nihei consume as he dreamed of writing his own science fiction? Still, it’s an interesting interview and even if you’ve never read the manga (like me) it still gives an interesting perspective on what made Knights of Sidonia.
