Mahiro Kyobashi is a student at Pirari Academy, a special school run by ALCA to train Logicalists who protect world peace. She is enrolled in Class 1-S alongside her classmates. Known for being technically minded, Mahiro has a deep fondness for Foreigners and is very interested in their culture. This interest extends to tinkering with and building various mechanical gadgets and gizmos, which she often carries with her.

Her personality is marked by high energy and a strong, almost extreme dedication to her projects and interests. When Mahiro focuses on something she wants to do, she pursues it with single-minded determination. However, her inventive spirit has a chaotic side, as the things she creates have a frequent tendency to malfunction and cause explosions. Despite this, her intentions with her inventions are consistently good.

Mahiro's role in the story is primarily as a supportive and colorful member of her class, bringing both technical skills and energetic enthusiasm to the group. Her relationship with her classmate Yayoi Tachibana is notably defined by this habit, as Yayoi often becomes angry with Mahiro due to the explosions caused by her inventions. Her other key relationships include her fellow students, particularly Nina Alexandrovna, who is a skilled but socially reserved Logicalist. As a Covenantor, Mahiro is paired with Foreigners named Selen, known as Preparing for Battle, Selen, and Dread, known as Main Armament Fire, Dread.
