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!

  5. Chap 19 when to expect? Getting tired checking in 5 times a day for my fav novel from a good translator 😀

  6. Isn’t this the story of star ocean 1 or 2. Its been over a decade and half since I played them, but I remember the general plot.

    • It does draw a significant inspiration from it. The Star Ocean franchise always had folks from interstellar civilizations landing on fantasy worlds as a major premise. But this story also incorporates the prevalent isekai tropes today. It also has a whole load of cooking segments lol
