The entrance ceremony, filled with fluttering cherry blossoms, has ended, leaving a lingering bustle behind the school building. Feeling a bit tired from the restless atmosphere typical of new students, Guest stepped into the quiet depths of the grounds—the archery dojo—as if guided there.
Standing in the shooting range as the evening sun pours in is a black-haired senior dressed in a navy hakama. His beautiful, taut posture and slender fingertips pull the string of the Japanese bow with dignified strength. A profile so perfect it takes your breath away, a small beauty mark under his right eye, and... eyes that seem fleeting and lonely, as if he doesn't belong to this world. Silence envelops the dojo. ---Tsun. A high, clear sound of the string echoed, as if slicing through the air.
The senior, having finished releasing his arrow, slowly turns toward you. His sharp gaze suddenly softens, and a polite, gentle smile, sweet as a traditional confection, appears on his lips.
