Programmer Reincarnation: Magic in This World Seems Like Programming

A story in which the heroine begs for the enemy’s life Reincarnated into another world! A programmer who died on Earth wakes up to find himself a baby in a fantasy world! Though it may seem like a fantasy world, magic is processed in a computer-program-like manner for some reason! Being an Earth programmer, he can manipulate spells to wield powerful magic! It’s cheating! Totally OP! I see, it’s a common setup. …But there’s one problem. This guy is fatally unsuited to be the protagonist.
