The spaceship which Imperial Galactic Navy Officer Alan Corinth helmed was shot down by a surprise attack during hyper-space navigation.
Completely due to freak coincidence, Alan became the only one in the ship to survive.
The severely damaged spaceship lost its navigation capabilities and plummeted onto a nearby planet.

Using an escape pod, Alan headed toward the planet alone.
Thus began Alan’s quest for survival on the underdeveloped planet utilizing the symbiotic nanomachines [Nanom] within his body.
Surprisingly, the planet was home to a thriving human civilization whose genetic code closely resembled Alan’s own.
Even while remaining at a loss due to being thrown into a world of swords and magic, he tries to live as best he could together with his newfound comrades.

What would Alan achieve this strange world?

The Sci-fi Fantasy story in a Medieval setting now begins!

    Man this translation is seriously garbage...

    Also what's with the arbitrary currency? First it was silver and gold, then it was guineas, it keeps switching back and forth between the two and there's absolutely no indication of the value of any of the three it's just completely random. Also... Guineas? In a fantasy world? In a sci-fi universe? what kind of retard thought of this?

    I'm pretty sure it's just the garbage translation and not whatever it said in the original raws, in fact I'm pretty sure they are using gold and silver or something of the sort, and there are no guineas. 400,000 guineas for mithril armor, how many fuckin coins would that be? Ain't nobody gonna use such a low denomination for trades in a fantasy world, how would they even carry all that around?
    @lehzer yeah it reminds me of Outlander too
    Interesting....I remembered there's a Hollywood movie that has the same premise. The MC is a male and the enemy aliens actually attached to his ship after they fought in space and the ship went down => Wreaking havoc on the unknown planet that is still in medieval ages. In the end, MC killed the enemy by forging a sword using metal scrapped from his ship. I couldn't remember the title unfortunately
    The bad isekai use being isekai'd as just a means of wish fulfillment which has little bearing on the plot.
    Just now this isekai got the message and being isekai'd is now part of the plot in chapter 16 not just in chapter 1.
    This should be quite a good manga.
    I thought chp17 is translated...
    and I was so excited..
    I want to come to an airtight bodysuit hnnngggggg
    This the first time seeing this type of Manga, im sure this Manga will be a Bang
    I've never read the Manga everyone else references [Gargantia]. But I have seen Starship Troopers and know a bit of WH40K, and this reminds me a lot of those sci-fi classics. With its big ominous Bugs (Like Tyrrannids Or ST's Bugs) and I enjoy seeing the Persian manner by which Alans military training guides him.

    My only real issue is minor grammatical mistakes here and there. But hey, those things happen.

    ill give this mango 10 stars if i can
    the usual plot twist would make the bugs actually are ancient / evolved humans due to nanomachines.

    Would be pretty refreshing if the bugs actually are real aliens

    Many people including myself have compared this series to Gargantia on the Verdurous Planet, and putting this in a spoiler in case you haven't seen it: No reason why evil predatory bug aliens can't just be evil predatory bug aliens.
    Lily mentioned Did i miss this or does it happen later ? This could be fun showing of Alan ...
    Oh thank god the manga sped through the novel's low points. Honestly I think the manga's presentation is far better than the novel's.
    This is basically Star Ocean theme and I love it!
    Gargantia sucked beyond words. It was at the level where Urobuchi only wrote the first and last episode and the rest was almost entirely completely inconsequential anime hijinks and poorly animated ecchi. The character design was done by a pornographic author for that purpose alone.
    This is pretty shallow and mirrors the usual isekai where the protagonist is just showing off his unearned superiority to the girls, but compared to Gargantia it's a superior work.
    It reminds me of Lord of the Ice Garden. I suppose the 'magic' will be something similar to what the LotIG had, seeing as it was capable of intercepting spaceship.
    I love Gargantia on the Verdurous planet, and this is basically that except it's not a planet covered in ocean. It's a lot faster paced and cuts out a lot of the learning of the language and culture for the MC, but instead has overarching developments with the conspiracy involved with the heroine. I would enjoy this more had I not recently watched Gargantia, since this manga hits a TON of similar story points and developments as Gargantia, I feel like I've already read this manga before.

    I hope I'm wrong and that this does get to deviate, but so far it seems way too similar to Gargantia to ignore (idk which came first, so Gargantia could have taken from this rather than the other way around) and seems a bit odd.
    Basically crappier self-insert Gargantia
    This is just fps player with better story and explanations.
    @degernase the usual plot twist would make the bugs actually are ancient / evolved humans due to nanomachines.

    Not really a spoiler because I haven't read the WN and the manga has barely touched on the subject but:
    I almost suspect that the alien bugs have some deeper reason/grudge behind their actions. They acted very intelligently when attempting to take over that ship in the flashback unrelated to MC and hesitated to inflict harm. There's also the fact that this world our MC got trapped on has been completely overlooked by this bug race, though to be fair the same can be said for the human race.
