The Irregular At Magic High School: Double Seven Arc Vol. 1

With only a few magic users in Japan, they’re a rare commodity and forced to attend one of nine magic-related schools, each of which focuses on a different aspect. Among these users is Tatsuya Shiba, a user who’s considered magically inept but manages through his unusual technical knowledge, combat abilities, and unique magical techniques, making him the “irregular” of The Irregular at Magic High School, a popular fantasy series written by Tsutomu Sato with illustrations by Tsuna Kitaumi.
The story continues as the Shibas become second year students! Their daily lives are once again packed with chaos with the arrival of new students. Among those new students is the representative of the first year class, Shippou Takuma, and the young Saegusa twin sisters Kasumi and Izumi, and fate has something in store for them.
