The spaceship which Imperial Galactic Navy Officer Alan Corinth helmed was shot down by a surprise attack during hyper-space navigation.

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?
