Surviving as the Academy's Weakest NPC

I possessed the weakest NPC in the game I had been playing for ten years, Lapis Academy!

Having possessed 'Theo,' the only son of the Academy’s strongest professor, I dreamed of quietly enjoying a golden spoon life of ease.
But lo and behold, when I avoided transferring into the Academy, the world ended and the game reset.
With no choice left, I entered the Academy!
To avoid getting swept up in danger, I tried to stay as far away as possible from the game's protagonist—but I kept getting entangled with them...!
The only skill I was given was the seemingly useless ‘Author’s Unique Skill.’
Thus begins the backdoor survival story of a fossil player struggling to survive in a nightmare-difficulty trash game!
