Aladdin is going nuts, love how he and those Ugos let out a roar at the beginning of the chapter.
So those Ugos can shoot out Harharl Infigar with their palms, given the size of their attack, it's comparable to the giant magoi cannon of Magnostadt.
So Mu knows that 3 magis exist, but doesn't know the name of the Kou magi? As the commander of an army he really should at least know the names of priority targets.
I think the next chapter or two Aladdin, Mogamett and Scheherazade will work out a solution, when suddenly the Kou empire invades.
