The Nippon Foundation included the manga on their list of "5 Recommended Manga Available in English" and wrote: "[c]omic scenes of characters tormenting each other are fun to read, with no sense of distaste. In an amusing way, the story shows how cultivating special skills can overcome adversity."[55] Writing for Le Figaro, Clémence Ballandras made a positive review about the series and wrote that it "combines the very specific universe of manga, with that of Harry Potter, while infusing a good dose of humor."[56] Rebecca Silverman of Anime News Network gave the first volume a B+. Silverman praised the series for its humor, calling it a "Harry Potter parody with overtones of One-Punch Man." Silverman, however, wrote that apart from Mash, the rest of the characters are "forgettable" and said that the art is "fairly unattractive", comparing it to Mob Psycho 100. Nevertheless, she concluded: "It doesn't look pretty, but it also doesn't need to, making this a good addition to the library of humor manga."[57]
Sheena McNeil of Sequential Tart gave the first volume a 7 out of 10. McNeil also noted the similarities with One-Punch Man and Harry Potter, praising as well its story and art, concluding: "I enjoyed this read a fair amount. It's low key hilarious. It has flaws, but it also has potential, and I look forward to where it goes from here."[58] In a review of the second volume, McNeil gave it a 8, and wrote: "[i]f you want action, humor, and magic, this story hits you over the head with all three."[59]
