From Jua Urembo, Mwana received advice on magic classes and magic forms as well as the intersection between these 2 dimensions and the sealing magic he was learning.
"Sealing magic, apart from sealing people, can also compress power. So don't just think of the Demon Sealing Portrait as a way to seal demons."
"What? Isn't it as direct? Before, you told me that the portrait art was a way to deal with the evil creatures of the world: the evil ghosts, demons, bloodsuckers, and the likes." Mwana naturally remembered the portrait as a technique and sealing magic in general had only been introduced to him as a means to seal things not to compress power.
"As you know different classes and forms of magic can have different effects on the same spell. Sealing magic is not all about just restraining people. In fact, in the same way it can restrain people, it can also restrain power effectively sealing it."
