Uchiru's manga / #fantasy(4)

how a magic school wizard lives is good. It reminds me a bit of running away from the hero with the antics between students and teachers. the fantasy is also a little different from the usual magic school novels(like harems,transported to novels/games), it has a bit of harry potter classic fantasy-like elements. There are mix-blood troll teachers, vampires, lich principal ,dwarf, elf with prosthetic limbs. There are talking trees who gives riddles, a half-demon priest student. 4 Tower dormitories groups that divides lineage such as blue dragon tower for royalty and high-rank nobles, Phoenix Tower for Priests of different denominations, White Tiger tower for Knights lineage, and Black turtle for new nobles, rich merchants, commoners and slaves. MC as a student must make use of his wits to survive a prison-like school with mad professors who enjoy tormenting students in the name of teaching by having students survive by their own with only hard black bread for meal, deceive students to escape then get caught, letting loose monsters while gathering materials and etc. There's NO big villain destroying the world, novel plots(future) that must be followed, harem vibes nor romance . It's literally just "how a magic school wizard live" full-on comedy.
