First of all, once more, the second season of Mahouka Koukou no Rettousei is still yet to be announced despite all the rumors that flooded the Internet. Numerous media outlets claim that they know the exact release date. However, this is not a confirmed fact. They must provide us a reference to the reliable source in that case. No one is aware of renewal, and, especially, about the release date, since there has been no official confirmation. To be sure of this, please visit the official website of the franchise. You won't find here any data on the subject.
On the other hand, the film, which came out on June 17, 2017, may serve a hint pointing to the fact that the franchise is still ongoing. So we just may assume that the second season is in the cards. Another good indicator in favor of the possible renewal is a reception by the target audience. According to MAL, The Irregular at Magic High School has a score of 7.76/10 ~ 200,000 votes. Though not a brilliant indicator, however, it is high enough. The viewers of Crunchyroll also left mostly positive reviews regarding the first season, estimating the series at 4.2 out of 5 stars. Thus, in general, the series has pretty high chances for a next season. But we will have to wait for the official announcement anyway.
Mahouka Koukou no Rettousei started off in April 2014 on Tokyo MX. Later, TVQ, BS11, AT-X, and other famous Japanese television networks began to broadcast the anime. MADHOUSE Inc. served as a developer of the television adaptation. Aniplex USA acted a licensor of the anime in North America. The first season of The Irregular at Magic High School consisted of twenty-six episodes. A movie titled The Irregular at Magic High School The Movie: The Girl Who Calls the Stars debuted on June 17, 2017. Summing up, we agree with the prevailing opinion the second season would happen. But we're waiting for the official announcement.
Mahouka Koukou no Rettousei: SummaryUpon results of WWIII, the world is split between four superpowers, USNA, New USSR, the Great Asian Alliance, and Japan. In this alternate world, the magic is more a technology rather than some sacred wisdom. However, few can use these skills since they spread through genetic. As a result, those children who possess magic abilities are forced to attend special schools. Each institution develops a particular magic aspect, from whence their specialization. There are nine schools of such kind in Japan.
Tatsuya Shiba attends one of such schools together with his sister Miyuki. Unfortunately, their skills are not equal despite the fact that they are siblings. As a result, they enroll in different courses depending on their abilities. Although Tatsuya feels a lack in magical capabilities, he is quite gifted in technical knowledge. Thus, he becomes an irregular in the school's standards of ranking.
