Tiara, a princess from the kingdom of Waleland, travels to the city of Mamkestell to attend a prestigious academy for those who practice magic like herself. After passing a test to prove her eligibility, Tiara reunites with her childhood friend Rosetta, who is also a student there. She then joins and meets Rosetta's group: the athletic Lavie, the reliable Ashley, and the bookish Lynette—all of whom Tiara quickly befriends. In this institution, students are placed into one of three ranks based on their test score: group Noir being the highest, followed by Rouge and Lapis. Tiara's group is ranked Lapis, and if that was not enough, those who fail while ranked Lapis face expulsion. Realizing their dire situation, Tiara urges everyone to start taking their activities more seriously. On top of this, Tiara has one more purpose for excelling at the academy: to become more like her elder sister, who is a very skilled singer. However, to reach the stage that she desires, she will have to overcome many challenges, along with her companions, as she continues her magical journey.

Yuuta Segawa has just started his freshman year of university. One day, his sister Yuri, who raised him after their parents died, asks him to take care of her daughters Hina, Sora and Miu while she and her husband go overseas on a business trip. Yuuta grudgingly accepts, but tragedy strikes when their plane goes missing and all passengers are presumed dead. In an effort to prevent the three girls from being split up, Yuuta goes against their family and takes them in, just as his sister took him in when he had no one else. Now the four find themselves in a new and peculiar situation: Yuuta must learn how to balance his new responsibilities—as the newest member of the Street Observation Research Society, a club for people watching, and also as a father figure—while Sora, Miu, and Hina come to terms with the loss of their parents.

Following the events of Scorched Halloween, the world is introduced to a terrifyingly powerful Strategic class magician. In an effort to uncover the identity of this person, the United States of the North American Continent (USNA) dispatches the most powerful asset in its arsenal to Japan on a covert mission—the elite magician unit Stars and its commander, Angie Sirius. At First High School, Tatsuya Shiba and his friends are having a farewell party for Shizuku Kitayama, who is leaving to study abroad in the USNA as part of an exchange program. In her place, the group welcomes the beautiful Angelina Lina Kudou Shields. Around the same time, Tatsuya is informed about the USNA's plan to uncover his true identity. Elsewhere in Tokyo, numerous reports arise of seemingly random bodies found drained of blood. Dubbed as the works of a vampire, it does not take long for Tatsuya to connect the dots and realize that it is almost impossible for the timing of these events to be mere coincidence.
