Yamaoki Rin is a 16 years old first-year high school student.
In this world where strange-looking monsters have started to appear, he participates in the monster subjugations as a survivor who possesses supernatural powers.
Rin’s skill is [Faker], a rare skill that can imitate the skills of other survivors. But its fatal flaw is skills that were imitated by [Faker] are dramatically weaker in comparison to the original abilities.
One day, Rin became aware of the true power of his failure skill [Faker] in a battle with a goblin.
This is a story about Rin, the lowest rank survivor, who awakens to his abilities and becomes stronger by defeating monsters with his cute partner.
