Wassup? It is I... unasked for and definitely unknown by any other name!
Definitely a Shonen premise. It almost feels like a literary adaptation of an anime. Which is, for sure, not a bad thing. It definitely appeals to its own section of writers. I already have a pretty good idea of the characters and I enjoy the imagery you have going on. I can definitely feel the fleshed-out scene you have in your mind.
I can almost feel you waiting for that "but..." I'll stop, I'll stop. So, I do have a few major criticisms. First off, the descriptions are just are smack dab amidst the paragraphs. There is little to no connection between them and the other information. It is not smoothly placed. To compare it with something, it's almost like putting a Pokemon profile description for each character after they are introduced. What needs to be done is the characteristics need to be introduced slowly, along with the movement of the main character's POV. What I mean is that instead of this: <“You’re late,” chides the dorm master, a sophisticated, lean, middle-aged man with vibrant amber eyes and auburn hair, “Did you, perchance, find the map confusing?”> you should instead put yourself in your main character's shoes, like so in this revised sentence: <“You’re late,” chides the dorm master. My eyes frantically look away from the imposing, sophisticated man in the seat facing me. In spite of reaching the years of a middle-aged man, he looks as lively as a teenager, with fiercely vibrant, amber eyes and auburn hair. “Did you, perchance, find the map confusing?” he said drolly, with unfortunately none of that youthful enthusiasm on his face.>
Now, I will admit that was a difficult thing to do. You generally want to keep profiles to a minimum, to be used sparingly and with a maximum impact. So I would recommend using them less, because people generally do not enjoy paragraphs of character profiles like I do.
Also, there is far too much exposition that could be revealed throughout the story. Take the time to ease the reader into it.
And most importantly, the story needs to be fleshed out. We are just jumping from place-to-place, without really focusing on each scene like the story. Impatience is doing it a disservice right now. Just take the time in each scene. Give them the impact they deserve. Break things up into sentences and really flesh out the interactions instead of leaping to the next tasty bit of action. Time skips, at least personally, should be avoided at the moment. We have barely received characterization. We know his profile, but it is his actions and his choices in tandem with thoughts as he socializes where we would truly get to know, and hopefully, sympathize.
Edit: Oh, and by the way, the disproportionate amount of criticisms to compliments is by no means representative of the proportions of successes and issues in your story. There are lots of great parts about it.
