Silent Witch Another: Kekkai no Majutsushi no Nariagari

After memorizing his magecraft textbook in a single week, Louis is accepted as a scholarship student at Minerva's Mage Training Institution. But surrounded by nobles, the rough and rowdy boy from a poor, remote village is treated as a problem child and feared for the way he trounces his opponents in magic battles. And yet Louis still finds teachers he respects and friends he can rely on as he grows into the man who will become a Sage. (Source: Yen Press)
