Martin

He is Alicia's older brother and a close NPC friend of Hiroshi Yūki, who works at the apple orchard. When Hiro first dives into the game world, this character, unfortunately, dies in an accident where a knife pierces his mouth. Later, when Hiro is imprisoned, he appears before him as a ghost. The ghost haunts Hiro to remind him of the "words of promise" they exchanged under the Kenura tree.

Eventually, Hiro and the ghost reconcile under the Kenura tree, and the ghost is able to pass on after hearing the promise again. After that, the ghost occasionally appears to help Hiro when he faces danger. However, if Hiro acts recklessly, the ghost can once again become a troublesome enemy.
