Comments of chapter undefined of Earth's Greatest Magus

Hey, to be fair, I do be out of shape. Also back in High School, for medical reasons i was underweight & didnt exercise much. I ate a metric ton, but thanks to a poor constitution & frequent nosebleeds, I never had enough nutrients to ever gain weight. That said, I hit sophmore year at a healthy weight due to not having PE thanks to being in Advanced Classes, put on muscle & got to the point by Senior year I was deadlifting 500lbs. So i have no doubt novel me will improve by leaps & bounds.

is this a filler arc? I gotta ask because it seems so irrelevant to the main plot the school arc is a bit alright I guess but not as interesting as emery's personal growth the only thing that actually matters is Shinta which may or may not contribute to main plot lines
