A world invaded by another dimension, and a world where heroes fight back. Kim, a weakling who is only good at drawing, summons 'Martin,' the imaginary hero he has drawn since childhood, into reality. A coming-of-age fantasy action story about a boy who protects the world with creativity and artistic passion, rather than brute force.
