Anyone know of anything out there with a similar Gate - Jietai Kare no Chi nite, Kaku Tatakeri, where it is two worlds interacting (at least semi)Openly? Another good example would be "Outbreak Company" or to a lesser extent, something like Zipang. Alternatively, An organized group/organization that does so (not something like The King of the Battlefield or that one where the guys whole class gets transported [forget the name]). Also not looking for something like "Modern Weapons Cheat in Another World", since they are just a product of the Protag's power, UNLESS the protag's power has to do with bringing people over. I know this one is kind of hard to pin down, sorry. Like I said, I know this one is a bit hard to pin down. Remember, I am not necessarily looking for just something where the protag is able to travel between worlds, but rather where the Story is about 2 different worlds openly/Semi-openly discovering and interacting/influencing each other. Like Gate-JSDF, or Outbreak Company. Alternatively something like Rune Troopers Nihonkoku Shoukan (WN) where a large group of people with advanced Tech are brought over. Could be a whole country like this, or even just a Mercenary Company, or something else. NOTES: 1): Decent Length (30+chapters or 2-3 Volumes, depending on chapter length), and/OR being actively translated (Has been updated in the last 1 - 2 months). I.E. I don't want something with 10-15 chapters that's not been updated since August 2016, but something with 5-10 chapters that's been update Mid Feb/Mar (or even the start) is perfectly fine. 2): No Hentai/Smut. Adult themes/Scenes are fine, but no blatant smut (I.E. a bedroom scene just for the sake of smut). 3): Harem tag is fine, but No Polygamy.
I've made the recommendations for out of space in on of my blog post, lets see... https://forum.novelupdates.com/blogs/911-oc-fanfic-titles-recommendation-002.2383/ A space marine trainee ship is attacked and survived barely by going into an unstable warp/black hole. And stranded into fantasy world. Mostly that's the background
Does war count as interaction? https://forum.novelupdates.com/threads/stuart-slades-the-salvation-war.5630/ Cuz' there'll be a lot of it in the first half.
Nihonkoku Shoukan (WN) - all of modern day Japan is transported to another world. There's a manga out if you want give it a quick check. I Came Back but the World is Still a Fantasy!? - kinda meets part of your request, but probably not what you want. There is a gate between Earth and a magicy world.
War itself, Ya (See Gate - JSDF) But this story? Hmmmm, Kind of? The idea sounds similar, but I don't think its quite the same thing I'm looking for. This seems more like a Darksiders kind of thing.
Didn't know about the Manga, How is its translation compared to the novel? XD and do you happen to know the diffrence between the WN and LN?
Well, a correction on the manga's translations. After reading a few chapters to catch up from when I left it, I see that the manga translator does have a problem with tenses. Other than that, it's ok.
If you don't mind paper books, there's the "Destroyermen" series by Taylor Anderson. To be honest, I haven't read it. I bought the first book of the series a while ago, but then I got sucked into asian fantasy so I never got around to it.
There'll be relationship and changes to all sides as the conflict continues. It's not just mindless battle, and in fact there's quite few of it displayed for something that long. Focus split between politic and science as things continue.
