Genso Suikoden: Tsumugareshi Hyaku-nen no Toki

A mother tells her son a tale of their ancestors battling monsters known as the Terrus Firma almost a century ago and that the monsters are due to return every hundred years. This tale inspired the young boy to grow up as a swordsman so he'd be prepared to fight these monsters when the time came. One day the young man was out with his friends, Myura and Zeno, when they get attacked by some hostile creatures. Fleeing from the monsters they find a hiding place where they are then met by a young man named Xephon. Xephon hands them a mysterious object and when they are told to touch a tree they are then transported back in time where they meet their ancestors who want to travel to the present time to help rid that future world of the incoming Terrus Firma. However the ancestors are not able to transport to the future time so the young swordsman asks his ancestors to take him under their wing and train him so he can rid the world of the Terrus Firma.
