Akuninzura shita B-kyuu Boukensha

Synopsis:

Dim, a B-rank traveler, should be only a horde character in the RPG "Splendid Dream". Nonetheless, by some coincidence, he saved a vagrant who was gone after by hooligans on the side of the road and chose to raise him as his dad. In any case, the vagrant ended up being the legend of this world, "Iska". The world's fate would be drastically altered by this choice.
