Kouji Mikagami is unremarkable at everything except video games. Summoned to another world, he is handed Copy Skill, an ability that mimics whatever his opponent uses, and expects a fast climb to the top. Instead the high priest who called him grades the gift trash-tier and throws him into the coliseum as a gladiator slave. With only that 'weakest' skill and his gamer instincts, Kouji has one way forward: beat the strongest female fighters sent against him and make a name in the arena.
