MÄR

Ginta Toramizu, a 14-year-old Tokyo junior high student with poor eyesight and a passion for fairy tales and video games, is unexpectedly transported to the fantastical world of MÄR Heaven. In this new realm, his physical limitations vanish, granting him enhanced strength and perfect vision. He encounters Dorothy, a 16-year-old witch who introduces him to magical artifacts called ÄRMs. Together they retrieve the sentient ÄRM Babbo, which Dorothy reluctantly gives to Ginta after deeming it too troublesome.

As Ginta explores MÄR Heaven with companions like farmer Jack, he discovers the world's darker aspects when targeted by thieves coveting Babbo. He later meets Alviss, who reveals having summoned Ginta using the Gate Keeper Clown ÄRM to combat the resurgent Chess Pieces organization. This group, led by King Orb and Queen Diana, previously attempted to conquer MÄR Heaven six years earlier. The narrative follows Ginta's growing involvement in the conflict against Chess Pieces while balancing his desire to return home.
