Yeah, and the thing is that he's still a low tier magician facing against high tiers. His only advantage is his knowledge of magic from the future that throw off most of his enemies.
But these outers are proving to be really cunning and not at all understimating their foes, as they know they're against nobles and all.
I reckon eventually there'll come a battle where the outers will be ready to counter Desir's abilities. That's when he will need the strenght of his party the most.
The first Great Demon's already here, the apocalyptic future might be closer than what Desir thought.
Heck, not so long ago we were talking about wining competitions and getting better scores at the academy. This kind of development gives off the feeling that time's running out for Desir and the great war is about to break out.
I don't know for you all, but seeing Desir being scolded by his party his kinda funny... and refreshing.
Desir's weakness is finaly revelated : holding everything by himself because he's afraid of the futur.
