Thanks to various magic, the human race has been saved from calamity many, many times. Retaining his memories from his previous life, a boy, Shin, was picked up by an old man known to the world as the "Magi."<br /><br />Shin was brought up by the Magi, who had retired to a secular place, as his own grandson. With the memories of his past life, he absorbed the Magi's craft and grew to be able to develop his own magic.<br /><br />Then, the grandfather told him he has to become independent when he reaches the age of 15.<br /><br />"Ah, I forgot to teach him common sense."<br /><br />The grandson who has grown beyond the level of normal people, lacked common sense; the common sense of the world. So to learn how to socialize, he goes to Earlshide Kingdom City to be admitted to Earlshide Advanced Magic Academy.<br /><br />RAWS: https://web-ace.jp/youngaceup/contents/1000015/
