Surviving The Tutorial With An OP Girlfriend

How does a relatively normal guy survive an impossible tutorial when his girlfriend keeps charging headfirst into danger just because she's built different? Nobody survives the Impossible Tutorial. That isn't an opinion. It's a fact. For years, Players chosen by the Game from every nation on Earth have entered the Tutorial seeking power, glory, and fame. Some chose Easy. Some chose Hard. A few ambitious idiots chose Nightmare, and somehow survived. But every person who chose Impossible died. Adam Colt knew this. His girlfriend Mei Mori knew it too, but she didn't care. One impulsive click later, she selected Impossible difficulty and vanished into the Tutorial. Adam had less than a second to make a decision. Let her go alone. Or follow her into a challenge nobody had ever survived. Now trapped inside a fantasy world on the highest difficulty setting imaginable, the two must complete the Tutorial's main questline: Protect the Human Kingdom, Survive the Demon King's invasion, and somehow defeat the Demon King himself. The problem? Impossible difficulty isn't called Impossible for nothing. Monsters are stronger. Resources are scarce. The rules are borderline unfair. And the Tutorial is hiding far more than it's willing to reveal. Fortunately, Mei is absurdly overpowered. Unfortunately, Adam has to survive long enough to benefit from it. — — — What to expect: • An OP gremlin of a girlfriend who treats impossible odds as a suggestion (not an actual gremlin…) • A capable protagonist who serves as the team's brain cell (he might only have a few left after all of Mei's antics) • Modern firearms in a fantasy world (powered by magic & gunpowder!) • RPG mechanics, classes, talents, and progression • A single romantic pairing (no harem) • Comedy, action, and plenty of bad decisions — Description from novelcodex.org
