Leila

Leila often takes on a human form that looks like a woman in her early twenties, which is very similar to her younger sister, Laika. Unlike Flatorte, who struggles to hide her dragon features, Leila can transform into a more mature-looking person without any trouble.

At home, Leila is laid-back and sloppy, even lounging in pajamas until just before leaving for school. However, at the academy, she is responsible and trusted by all the students. She is deeply caring toward her younger sister and is admired by everyone for her strength and leadership. Sometimes, she has a mischievous or slightly mean sense of humor, especially in her exchanges with Flatorte.

Leila is over 300 years old, but a closer guess is around 370–379 years old based on story details. She spent about 30 years wandering after reaching the age to attend school before enrolling in Red Dragon Girls' Academy.

Leila is known as the "Strongest Student Council President" and once held the nickname "King of Destruction." She defeated many upperclassmen as a new student and became student council president in her first year. No one at the academy was stronger than her, and she was even called "the once-in-500-years genius."

• Laika: Leila's younger sister. She loves and dotes on Laika, but Laika is actually better at sports and was always stronger in fights when they were kids.
• Flatorte: Daughter of the Blue Dragon and her longtime rival. While often seen as opponents, their relationship is more like friendly rivals who tease each other.
• Husband: Leila decided to marry her old childhood friend after they met again. He works at the village office.

School Life at Red Dragon Girls' Academy

Leila entered Red Dragon Girls' Academy as a fifth-grader after thirty years of traveling. She quickly beat many older students and collected many victory badges, soon earning the reputation of "Shadow President," and then officially became student council president in her first year. From then on, she led the school, gathered all the members of the student council herself, and was adored as the strongest leader.

When she became a sixth-grader, Leila handed over the student council president role to Sadie and finally faced her sister Laika in a decisive showdown. After graduation, she left on another journey just three days before Laika welcomed new students as a third-grader.

Reunion and Marriage

In the main story, Leila meets her childhood friend after 80 years. They quickly hit it off again, begin dating, and decide to get married. Her husband now works for the village office.

Friendly Rivalry with Flatorte

Leila and Flatorte have known each other since they were young. Flatorte always tried to compete with her, but Leila was able to come up with witty and unbeatable replies. Their rivalry was more about being close, teasing friends than true enemies.

• Leila is about 70–79 years older than Laika.
• She prefers to stay lazy at home but is super responsible at school.
• Her nickname changed from "King of Destruction" to just "President" as she earned respect.
