Mizui is a water-based spell from Roland. After saying the incantation and the name of the spell, a stream of water shoots out from the glyph. The spell lacks destructive power and is therefore rarely used in battle.
"What I seek is the water cloud, Mizui!"(Motomeru wa Sui-un, Mizui!) is the incantation for the spell. Mizui's glyph appears to be a cross over a circle.
