Circlet Princess: First Bout

In a near-future setting, a widely adopted advanced AR technology called the Mixed Reality System has given rise to a new sport. One of its most popular forms, Circlet Bout, has gained a strong following among high school girls, with top athletes becoming nationally recognized. Yuuka Sasaki has recently enrolled at Saint Union Academy, where the school's Circlet Bout team is struggling. The question remains whether she can help restore the team's former strength.
