I think this is first mecha series that has pilot suit that dudbe as masturbate skin suit. Lol And that mechanic chick... like she always wearing skin suit... constants orgasm on work? Those suit can filter the piss to save-to-drink water... so she can just piss then drink it whenever she need water while working on fixing the mechs... convenient.
Collection of images from what looks like different artists based off of Knights of Sidonia. Not all are well done but I would love to see more Izana Shinatose hentai.
@ UnknownDestroyer. Actually, UD, if I recall the explanation given in the show, the "Bigender" types like Izuna will have their bodies change to match, once s/he finds a life partner. Therefore, Izuna sprouting a penis is entirely withing the realm of canon possibility. (What lies inside hir pants right now, BEFORE making that change, is an interesting question. Some thumb-sized organ too big to be a clit and too small to be a penis? Something more like a Barbie doll with a urethra?)
You have a valid point though: So far though (I'm up to episode 9 now) Izuna seems rather interested in our male lead, so yeah, one assumes s/he would be shifting to be more feminine, along with the corresponding plumbing, rather than shifting to compliment a female partner.
