The Strongest Sage with the Weakest Crest #14

Plot

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 backward, 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 is out to stop them from destroying humanity!

An army of wooden automatons has appeared at the border between the Eis Kingdom and the neighboring Syhill Empire. Matthias suspects demonic involvement, but getting to the bottom of the invasion means infiltrating the empire, where he finds a tribe of demons thought to be long extinct! Who will emerge victorious after the fierce battle?
