For thousands of years, there has been a cycle: a Demon King rises and conquers, and a Hero is reborn a hundred years later to defeat him. Each time, civilisations are ground to dust beneath the Demon King's hordes, but humanity has remained secure in the belief that a Hero of legend will always save them. There's just one slight problem. It's only been 23 years since the Demon King's latest rise, and this time, he's already conquered more than half the world. If humanity simply waits for the Hero's return, there may be no world left for him to save.

And so, Yui Shaw sets out with an ambitious plan. A 10-step plan.

She'll find a way to obtain the Hero's legendary sword. She'll earn obscure classes, gain levels, and increase her skills. She'll travel to the meticulously-crafted dungeons that seem designed for one specific Hero to complete. And, if she's truly (un)fortunate, she might even find a fairy.
