Review Detail of Sangabriel in The Magician of Sound

It started okay, but it has became ridiculous. 1st. The power classification, is sloppy at best, instead of S,A,B or C class Magicians it should be talent or something like that, we dont have a clear distintion of power with the characters. 2nd. The "civil war" development is really bad, at least at my eyes. Goverment useless, ok, 3 main familys, where we have 1 which power is mainly about an S rank Magician that's almost dead, and it's alive only because of medicine, that has fought with the MC for something like 5 minutes and it's already puking blood. The second family, the kudo, almost got their heiress killed but are like, well ok, it has nothing to do with us or something, the family with the best weapons in the country it's the most useless, or atleast that's what the author is making me believe. and the third family has their heir, really away from them without apparent reason. And the 3rd. We have a Sound magician, that for what my limited understanding it's basically controlling vibrations, and we dont have a magic about a vibration sword or that he's unable to feel the monsters underground??? it's a bit weird for me, but ok, this one is more me complaining that another thing.
