The Irregular at Magic High School the Movie: The Girl Who Calls the Stars

Tatsuya Shiba and his sister Miyuki along with their friends, including Erika, Leonhard, Mizuki, Mikihiko, and Honoka, arrived at a villa in the Bonin Islands to enjoy their spring break. The group was excited, looking forward to a relaxing getaway amidst the serene natural beauty of the islands.

Their peaceful retreat was suddenly interrupted by a message from the military. Tatsuya received an alarming order to destroy an asteroid that was on a collision course with Earth, marking the immediate end of their vacation.

While traveling to Minamitate Island, Tatsuya and his friends unexpectedly discovered a mysterious girl named Kokoa hidden in their aircraft. She revealed her identity as part of the Watatsumi series, a group of modified magicians born from a risky experimental project.

Determined to learn more about Kokoa and the Minamitate facility, Tatsuya, with the assistance of Miyuki, infiltrated the place. There, they discovered the sinister project called 'Meteorite Fall,' designed to unleash catastrophic strategic-class magic upon the world.

Meanwhile, military operatives from the USNA, under the command of Angelina Kudou Shields, initiated a secret mission to dismantle the research facility. They aimed to prevent the dangerous development of the Strategic-class Magic before it could cause widespread chaos.

During Tatsuya's rescue of the Watatsumi girls, he uncovered a shocking truth: the Meteorite Fall experiment had led to the descent of a USNA space station, Seventh Plague, which carried uranium bombs. This revelation precipitated a race against time to avert an impending disaster.

Erika and Leonhard found themselves in an intense battle against USNA magicians Ralph Algol and Hardy Mirphak. They fought fiercely to protect the research facility, but the odds were against them until Katsuto Jyumonji joined the fray to assist.

In a coordinated effort, Tatsuya and his allies managed to eliminate the gigantic CAD machine, which was central to the Meteorite Fall experiment. Their success prevented any further attempts at deploying the catastrophic magic and averted disaster for the region.

As tensions escalated, Tatsuya reached out to Angelina for assistance regarding the crisis presented by the space station. After receiving approval, he embarked on a mission to destroy the Seventh Plague before it could crash back into Earth, a risky but necessary endeavor.

Tatsuya successfully accomplished his goal, destroying the orbital space station just in time. The obliteration caused a spectacular display of auroras, illuminating the night sky in brilliant colors, symbolizing hope amidst the chaos.

With the crisis finally behind them, Kokoa joyfully reunited with her fellow Watatsumi girls at the Kanto branch of the Magic Association. Honoka, Shizuku, Mayumi, and Mari Watanabe were there to celebrate their safety and the end of the tumultuous events.
