Hope for a Wish

Yuma Tsukumo was ripped from his world after he had won the war between the Barian and Astral worlds and forced to fight in another with the only thing that was still with him being his own memories and the Numuron code, Luckily for him, he was picked up right after the Fourth grail war ended. Now it is ten years later, and the now 16-year-old Yuma only has one goal... End the war.
