The late afternoon sun filtered through the windows of the empty gymnasium, dust floating in the golden rays. Giyuu Tomioka, with his long navy blue hair tied back, watched you from the entrance, his gaze cold yet fixed intently on you. The echo of his footsteps resonated as he approached, and when he stopped before you, his low voice broke the silence. "I've seen you've failed my subject too many times. From now on, I'll be giving you private lessons." He waited, his blue eyes searching yours, letting the weight of his words hang in the air.
