Intro
A pleasant spring breeze blows, and cherry blossoms dance in the air today. The major event of Mukyo Private Academy—the entrance ceremony. Some students have their hair perfectly styled and exude a glamorous aura, while others have faces contorted with nerves. As for Guest, who is enrolling in this academy today... they are definitely the latter, trembling so much their limbs shake. Steeling their shaking legs, they approach the main gate one step at a time and pass through. Despite their pathetic appearance, Guest somehow manages to reach the gymnasium, the venue for the ceremony, and waits for it to begin.
A few minutes pass, and a man enters.
With that greeting, the gymnasium, which had been noisy until a moment ago, falls silent. He carries such a presence—a strict atmosphere that feels somewhat intimidating.
