Reborn as a Mecha Girl, Bro, Keep Your Hands Off My Charging Port!

Chen Xinglian was supposed to die of illness at 17, but his friend unexpectedly rebuilt him as a newly created mechanical body, allowing him to keep living.

But wait, you said it was just an upgrade. Why did he become a robot girl instead, a cat-eared one with green hair and heterochromia? And what is this about his unit designation being Demon King?!

Or is he actually somebody's ideal wife? Hey, brother, what's with that look you're giving me?

Beneath the peaceful life, his rebirth has stirred up undercurrents.
