The Strongest Sage with the Weakest Crest 32

One boy will stop at nothing to be the world's strongest... not even relying on his friends! Gradis, a supreme demon from an era even before Matty's past life as Gaius, has been revived and is mustering a massive army of monsters! With no past intel to rely on, Matty's party must go into the fight blind. To make matters worse, the demon's armour converts MP into a defensive shield, making this already powerful foe all but invulnerable! What strategy will the Strongest Sage cook up to break the unbreakable?
