Origin
Japan
Saegusa Izumi is one of Mayumi's younger twin sisters. Izumi is described as a feminine girl with hair in a straight bob that goes down to her shoulders and bangs that reach her eyebrows. She is noted to be an indoors type person or a bookworm. Izumi usually conceals her thoughts and feelings behind an unreadable and gentle smile, and she rarely lets her emotions run wild.

The Irregular at Magic High School
In the dawn of the 21st century, magic, long thought to be folklore and fairy tales, has become a systematized technology and is taught as a technical skill. In First High School, the institution for magicians, students are segregated into two groups based on their entrance exam scores: "Blooms," those who receive high scores, are assigned to the First Course, while "Weeds" are reserve students assigned to the Second Course. Mahouka Koukou no Rettousei follows the siblings, Tatsuya and Miyuki Shiba, who are enrolled in First High School. Upon taking the exam, the prodigious Miyuki is placed in the First Course, while Tatsuya is relegated to the Second Course. Though his practical test scores and status as a "Weed" show him to be magically inept, he possesses extraordinary technical knowledge, physical combat capabilities, and unique magic techniques—making Tatsuya the irregular at a magical high school.

The Irregular at Magic High School: Visitor Arc
Miyuki's classmate Shizuku Kitayama is on her way to study abroad. For magicians, this is normally impossible, since allowing the genes of someone who can use magic outside their home country's borders is tantamount to giving up national secrets. But it's allowed to happen in one case-exchange programs. And that's how Angelina has arrived in Japan from the USNA to study at First High. But it seems she's a part of something much bigger than a simple cultural exchange!
