In this manga adaptation of the popular light novel series, the world's strongest sage will stop at nothing to get stronger...not even reincarnation! Is former Strongest Sage Matthias's fight to protect mankind finally over...or is it just beginning?! The magician once known as a great sage has—in search of greater power—reincarnated himself far into the future. His new self has acquired the strongest crest for magical combat, but in an era where magic principles are all backwards, that crest is looked down on as the "crest of failure..." It turns out that evil demons were the ones who sowed disinformation and confusion about crests and magic, and now, Matthias and his party are off to a new land in pursuit of a device that will lead them to a certain powerful demon! However, entering that territory requires that all party members reach at least A-rank with the guild. Matthias and friends are quickly on their way to higher ranks, until an unimaginably powerful monster stands in their way!
