In order to find the truth behind his brother's death, the ordinary human Al was accidentally transported to Durmstrang Magic School by a strange-looking triangular magic circle, and accidentally replaced the original transfer student Greengrass from Hogwarts. In the world of pure-blood wizards, he was the only one who understood that he was an alien "Muggle" among wizards. Moreover, there is a fatal problem for him who is a Muggle - he does not know magic and is destined to be unable to use spells as well as other real wizards. If this continues, will it be a matter of time before he is exposed?
But what he didn't expect was that the triangular pendant that followed him to this magical world seemed to be able to instill in him the magic power from the outside world for him to control. Therefore, in order not to expose his "Muggle" identity, he worked hard to study the mind-numbing words and assiduously studied the esoteric black magic. He successfully became a member of the "Wizards" and successfully defeated the four witches of the Supreme Council of Dark Witches. He was awarded the title of "The Great Successor of Grindelwald" and a group of followers who worship Grindelwald's black magic...
But what puzzled him was that the new introductory black magic professor had the exact same face as his brother! And the last chairman, no one has ever seen her true face, or there is another possibility... Everyone who has seen her is dead...
